Invention of digital technology has lead to increase in the number of images that can be stored in digital format. So searching and retrieving images in large image databases has become more challenging. From the last few years, Content Based Image Retrieval (CBIR) gained increasing attention from researcher. CBIR is a system which uses visual features of image to search user required image from large image
database and user’s requests in the form of a query image. Important features of images are colour, texture and shape which give detailed information about the image. CBIR techniques using different feature extraction techniques are discussed in this paper.
International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research and review articles in the fields of Computer Science, Neural Networks, Electrical Engineering, Software Engineering, Information Technology, Mechanical Engineering, Chemical Engineering, Plastic Engineering, Food Technology, Textile Engineering, Nano Technology & science, Power Electronics, Electronics & Communication Engineering, Computational mathematics, Image processing, Civil Engineering, Structural Engineering, Environmental Engineering, VLSI Testing & Low Power VLSI Design etc.

With many possible multimedia applications, content-based image retrieval (CBIR) has recently gained more interest for image management and web search. CBIR is a technique that utilizes the visual content of an image, to search for similar images in large-scale image databases, according to a user’s concern. In image retrieval algorithms, retrieval is according to feature similarities with respect to the query, ignoring the similarities among images in database. To use the feature similarities information, this paper presents the k-means clustering algorithm to image retrieval system. This clustering algorithm optimizes the relevance results by firstly clustering the similar images in the database. In this paper, we are also implementing wavelet transform which demonstrates significant rough and precise filtering. We also apply the Euclidean distance metric and input a query image based on similarity features of which we can retrieve the output images. The results show that the proposed approach can greatly improve the efficiency and performances of image retrieval.
In this project, we proposed a Content Based Image Retrieval (CBIR) system which is used to retrieve a
relevant image from an outsized database. Textile images showed the way for the development of CBIR. It
establishes the efficient combination of color, shape and texture features. Here the textile image is given as
dataset. The images in database are loaded. The resultant image is given as input to feature extraction
technique which is transformation of input image into a set of features such as color, texture and shape.
The texture feature of an image is taken out by using Gray level co-occurrence matrix (GLCM). The color
feature of an image is obtained by HSI color space. The shape feature of an image is extorted by sobel
technique. These algorithms are used to calculate the similarity between extracted features. These features
are combined effectively so that the retrieval accuracy and recall rate is enhanced. The classification
techniques such as Support Vector Machine (SVM) are used to classify the features of a query image by
splitting the group such as color, shape and texture. Finally, the relevant images are retrieved from a large
database and hence the efficiency of an image is plotted.The software used is MATLAB 7.10 (matrix
laboratory) which is built software applications

Evaluation of Euclidean and Manhanttan Metrics In Content Based Image Retriev...IJERA Editor
Content-based Image Retrieval is all about generating signatures of images in database and comparing the signature of the query image with these stored signatures. Color histogram can be used as signature of an image and used to compare two images based on certain distance metric. Distance metrics Manhattan distance (L1 norm) and Euclidean distance (L2 norm) are used to determine similarities between a pair of images. In this paper, Corel database is used to evaluate the performance of Manhattan and Euclidean distance metrics. The experimental results showed that Manhattan showed better precision rate than Euclidean distance metric. The evaluation is made using Content based image retrieval application developed using color moments of the Hue, Saturation and Value(HSV) of the image and Gabor descriptors are adopted as texture features.
Content-Based Image Retrieval (CBIR) systems have been used for the searching of relevant images in various research areas. In CBIR systems features such as shape, texture and color are used. The extraction of features is the main step on which the retrieval results depend. Color features in CBIR are used as in the color histogram, color moments, conventional color correlogram and color histogram. Color space selection is used to represent the information of color of the pixels of the query image. The shape is the basic characteristic of segmented regions of an image. Different methods are introduced for better retrieval using different shape representation techniques; earlier the global shape representations were used but with time moved towards local shape representations. The local shape is more related to the expressing of result instead of the method. Local shape features may be derived from the texture properties and the color derivatives. Texture features have been used for images of documents, segmentation-based recognition,and satellite images. Texture features are used in different CBIR systems along with color, shape, geometrical structure and sift features.
Color and texture based image retrievaleSAT Journals
Abstract Content-based image retrieval (CBIR) is an vital research area for manipulating bulky image databases and records. Alongside the conventional method where the images are searched on the basis of words, CBIR system uses visual contents to retrieve the images. In content based image retrieval systems texture and color features have been the primal descriptors. We use HSV color information and mean of the image as texture information. The performance of proposed scheme is calculated on the basis of precision, recall and accuracy. As an effect, the blend of color and texture features of the image provides strong feature set for image retrieval. Keywords: image retrieval, HSV color space, color histogram, image texture.

Web Image Retrieval Using Visual Dictionaryijwscjournal
In this research, we have proposed semantic based image retrieval system to retrieve set of relevant images for the given query image from the Web. We have used global color space model and Dense SIFT feature extraction technique to generate visual dictionary using proposed quantization algorithm. The images are transformed into set of features. These features are used as inputs in our proposed Quantization algorithm for generating the code word to form visual dictionary. These codewords are used to represent images semantically to form visual labels using Bag-of-Features (BoF). The Histogram intersection method is used to measure the distance between input image and the set of images in the image database to retrieve similar images. The experimental results are evaluated over a collection of 1000 generic Web images to demonstrate the effectiveness of the proposed system.

An Unsupervised Cluster-based Image Retrieval Algorithm using Relevance FeedbackIJMIT JOURNAL
Content-based image retrieval (CBIR) systems utilize low level query image feature as identifying similarity between a query image and the image database. Image contents are plays significant role for image retrieval. There are three fundamental bases for content-based image retrieval, i.e. visual feature extraction, multidimensional indexing, and retrieval system design. Each image has three contents such as: color, texture and shape features. Color and texture both plays important image visual features used in Content-Based Image Retrieval to improve results. Color histogram and texture features have potential to retrieve similar images on the basis of their properties. As the feature extracted from a query is low level, it is extremely difficult for user to provide an appropriate example in based query. To overcome these problems and reach higher accuracy in CBIR system, providing user with relevance feedback is famous for provide promising solutio

SEMANTIC IMAGE RETRIEVAL USING MULTIPLE FEATUREScscpconf
In Content Based Image Retrieval (CBIR) some problem such as recognizing the similar
images, the need for databases, the semantic gap, and retrieving the desired images from huge
collections are the keys to improve. CBIR system analyzes the image content for indexing,
management, extraction and retrieval via low-level features such as color, texture and shape.
To achieve higher semantic performance, recent system seeks to combine the low-level features
of images with high-level features that conation perceptual information for human beings.
Performance improvements of indexing and retrieval play an important role for providing
advanced CBIR services. To overcome these above problems, a new query-by-image technique
using combination of multiple features is proposed. The proposed technique efficiently sifts through the dataset of images to retrieve semantically similar images.

EFFECTIVE SEARCH OF COLOR-SPATIAL IMAGE USING SEMANTIC INDEXINGIJCSEA Journal
Most of the data stored in libraries are in digital form will contain either pictures or video, which is tough to search or browse. Methods which are automatic for searching picture collections made large use of color histograms, because they are very strong to wide changes in viewpoint, and can be calculated trivially. However, color histograms unable to present spatial data, and therefore tend to give lesser results. By using combination of color information with spatial layout we have developed several methods, while retrieving the advantages of histograms. A method computes a given color as a function of the distance between two pixels, which we call a color correlogram. We propose a color-based image descriptor that can be used for image indexing based on high-level semantic concepts. The descriptor is
based on Kobayashi’s Color Image Scale, which is a system that includes 130 basic colors combined in 1180 three-color combinations. The words are represented in a two dimensional semantic space into groups based on perceived similarity. The modified approach for statistical analysis of pictures involves transformations of ordinary RGB histograms. Then a semantic image descriptor is derived, containing semantic data about both color combinations and single colors in the image.
Query Image Searching With Integrated Textual and Visual Relevance Feedback f...IJERA Editor
There are many researchers who have studied the relevance feedback in the literature of content based image
retrieval (CBIR) community, but none of CBIR search engines support it because of scalability, effectiveness
and efficiency issues. In this, we had implemented an integrated relevance feedback for retrieving of web
images. Here, we had concentrated on integration of both textual features (TF) and visual features (VF) based
relevance feedback (RF), simultaneously we also tested them individually. The TFRF employs and effective
search result clustering (SRC) algorithm to get salient phrases. Then a new user interface (UI) is proposed to
support RF. Experimental results show that the proposed algorithm is scalable, effective and accurated
Content based Image Retrieval from Forensic Image DatabasesIJERA Editor
Due to the proliferation of video and image data in digital form, Content based Image Retrieval has become a prominent research topic. In forensic sciences, digital data have been widely used such as criminal images, fingerprints, scene images and so on. Therefore, the arrangement of such large image data becomes a big issue such as how to get an interested image fast. There is a great need for developing an efficient technique for finding the images. In order to find an image, image has to be represented with certain features. Color, texture and shape are three important visual features of an image. Searching for images using color, texture and shape features has attracted much attention. There are many content based image retrieval techniques in the literature. This paper gives the overview of different existing methods used for content based image retrieval and also suggests an efficient image retrieval method for digital image database of criminal photos, using dynamic dominant color, texture and shape features of an image which will give an effective retrieval result.
Low level features for image retrieval basedcaijjournal
In this paper, we present a novel approach for image retrieval based on extraction of low level features
using techniques such as Directional Binary Code (DBC), Haar Wavelet transform and Histogram of
Oriented Gradients (HOG). The DBC texture descriptor captures the spatial relationship between any pair
of neighbourhood pixels in a local region along a given direction, while Local Binary Patterns (LBP)
descriptor considers the relationship between a given pixel and its surrounding neighbours. Therefore,
DBC captures more spatial information than LBP and its variants, also it can extract more edge
information than LBP. Hence, we employ DBC technique in order to extract grey level texture features
(texture map) from each RGB channels individually and computed texture maps are further combined
which represents colour texture features (colour texture map) of an image. Then, we decomposed the
extracted colour texture map and original image using Haar wavelet transform. Finally, we encode the
shape and local features of wavelet transformed images using Histogram of Oriented Gradients (HOG) for
content based image retrieval. The performance of proposed method is compared with existing methods on
two databases such as Wang’s corel image and Caltech 256. The evaluation results show that our
approach outperforms the existing methods for image retrieval.

A COMPARATIVE ANALYSIS OF RETRIEVAL TECHNIQUES IN CONTENT BASED IMAGE RETRIEVALcscpconf
Basic group of visual techniques such as color, shape, texture are used in Content Based Image Retrievals (CBIR) to retrieve query image or sub region of image to find similar images in image database. To improve query result, relevance feedback is used many times in CBIR to help user to express their preference and improve query results. In this paper, a new approach for image retrieval is proposed which is based on the features such as Color Histogram, Eigen Values and Match Point. Images from various types of database are first identified by using edge detection techniques .Once the image is identified, then the image is searched in the particular database, then all related images are displayed. This will save the retrieval time. Further to retrieve the precise query image, any of the three techniques are used and comparison is done w.r.t. average retrieval time. Eigen value technique found to be the best as compared with other two techniques.

COMPARATIVE ANALYSIS OF ROUTING PROTOCOLS IN MOBILE AD HOC NETWORKSijcax
A Mobile Ad Hoc Network (MANET) is a collection of mobile nodes that want to communicate without any
pre-determined infrastructure and fixed organization of available links. Each node in MANET operates as
a router, forwarding information packets for other mobile nodes. There are many routing protocols that
possess different performance levels in different scenarios. The main task is to evaluate the existing routing
protocols and finding by comparing them the best one. In this article we compare AODV, DSR, DSDV,
OLSR and DYMO routing protocols in mobile ad hoc networks (MANETs) to specify the best operational
conditions for each MANETs protocol. We study these five MANETs routing protocols by different
simulations in NS-2 simulator. We describe that pause time parameter affect their performance. This
performance analysis is measured in terms of Packet Delivery Ratio, Average End-to-End Delay,
Normalized Routing Load and Average Throughput.

A Multi Criteria Decision Making Based Approach for Semantic Image Annotation ijcax
Automatic image annotation has emerged as an important research topic due to its potential application on
both image understanding and web image search. This paper presents a model, which integrates visual
topics and regional contexts to automatic image annotation. Regional contexts model the relationship
between the regions, while visual topics provide the global distribution of topics over an image. Previous
image annotation methods neglected the relationship between the regions in an image, while these regions
are exactly explanation of the image semantics, therefore considering the relationship between them are
helpful to annotate the images. Regional contexts and visual topics are learned by PLSA (Probability
Latent Semantic Analysis) from the training data. The proposed model incorporates these two types of
information by MCDM (Multi Criteria Decision Making) approach based on WSM (Weighted Sum
Method). Experiments conducted on the 5k Corel dataset demonstrate the effectiveness of the proposed
model.
On Fuzzy Soft Multi Set and Its Application in Information Systems ijcax
Research on information and communication technologies have been developed rapidly since it can be
applied easily to several areas like computer science, medical science, economics, environments,
engineering, among other. Applications of soft set theory, especially in information systems have been
found paramount importance. Recently, Mukherjee and Das defined some new operations in fuzzy soft
multi set theory and show that the De-Morgan’s type of results hold in fuzzy soft multi set theory with
respect to these newly defined operations. In this paper, we extend their work and study some more basic
properties of their defined operations. Also, we define some basic supporting tools in information system
also application of fuzzy soft multi sets in information system are presented and discussed. Here we define
the notion of fuzzy multi-valued information system in fuzzy soft multi set theory and show that every fuzzy
soft multi set is a fuzzy multi valued information system.
Web is a collection of inter-related files on one or more web servers while web mining means extracting
valuable information from web databases. Web mining is one of the data mining domains where data
mining techniques are used for extracting information from the web servers. The web data includes web
pages, web links, objects on the web and web logs. Web mining is used to understand the customer
behaviour, evaluate a particular website based on the information which is stored in web log files. Web
mining is evaluated by using data mining techniques, namely classification, clustering, and association
rules. It has some beneficial areas or applications such as Electronic commerce, E-learning, Egovernment, E-policies, E-democracy, Electronic business, security, crime investigation and digital library.
Retrieving the required web page from the web efficiently and effectively becomes a challenging task
because web is made up of unstructured data, which delivers the large amount of information and increase
the complexity of dealing information from different web service providers. The collection of information
becomes very hard to find, extract, filter or evaluate the relevant information for the users. In this paper,
we have studied the basic concepts of web mining, classification, processes and issues. In addition to this,
this paper also analyzed the web mining research challenges.

Visually impaired people face many problems in their day to day lives. Among them, outdoor navigation is
one of the major concerns. The existing solutions based on Wireless Sensor Networks(WSN) and Global
Positioning System (GPS) track ZigBee units or RFID (Radio Frequency Identification) tags fixed on the
navigation system. The issues pertaining to these solutions are as follows: (1) It is suitable only when the
visually impaired person is commuting in a familiar environment; (2) The device provides only a one way
communication; (3) Most of these instruments are heavy and sometimes costly. Preferable solution would
be to make a system which is easy to carry and cheap.
The objective of this paper is to break down the technological barriers, and to propose a system by
developing an Android App which would help a visually impaired person while traveling via the public
transport system like Bus. The proposed system uses an inbuilt feature of smart phone such as GPS
location tracker to track the location of the user and Text to Speech converter. The system also integrates
Google Speech to Text converter for capturing the voice input and converts them to text. This system
recommends the requirement of installing a GPS module in buses for real time tracking. With minor

With the great development that, modern medical technology is witnessing today, medical devices and
equipment have become a basic pillar of any healthcare system in the world and cannot be dispensed with,
so we find competition between the major companies that manufacture medical devices and equipment
resulting in a huge variety of complex modern medical technologies. These medical devices and equipment
require high accuracy in manufacturing and packaging in addition to operation, maintenance, and followup, because any error in any of the previous stages will have bad consequences for the patients and the
health system, there are many accidents that have led to some deaths. Therefore, we find that many medical
device producers and medical companies in addition to health service providers seek to find systems and
protocols to reduce accidents resulting from medical devices. As a result, many systems have recently
appeared that seek to protect from the dangers of medical devices and equipment. This research aims to
conduct a study of the effects of international standards on the safety of medical devices and equipment
and reduce their risks. By counting the international standards in force in the Kingdom of Saudi Arabia
that are applied by the Saudi Food and Drug Authority, making questionnaires, and distributing them to
health service providers and regulatory bodies for medical devices and equipment, considering the data,

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Abstract
Invention of digital technology has lead to increase in the number of images that can be stored in digital
format. So searching and retrieving images in large image databases has become more challenging. From
the last few years, Content Based Image Retrieval (CBIR) gained increasing attention from researcher.
CBIR is a system which uses visual features of image to search user required image from large image
database and user’s requests in the form of a query image. Important features of images are colour,
texture and shape which give detailed information about the image. CBIR techniques using different
feature extraction techniques are discussed in this paper.
Keywords
CBIR; colour feature; texture feature shape feature.
1.Introduction
For efficient services in all fields such as government, academics, hospitals, crime prevention,
engineering, architecture, journalism, fashion and graphic design use images. Due to the
popularity of these types of digital image database becomes huge database, and to search and
retrieve required image from the huge database becomes difficult and time consuming. To solve
these problems traditionally text-based retrieval is used. In a computer system for browsing,
searching and retrieving images from the huge database of digital images retrieval system is used.
To search images, a user provides query terms of keyword and the system will return images
similar to the query.
In text based image retrieval keywords, label, tag or any other information is associated with the
image and using this metadata image retrieval is performed. In this method query is entered in
terms of text. But, there are some drawbacks of this type of an image retrieval system. Annotation
of each image in the database requires domain experts who add label or other information to the
image. Use of different keywords for annotation of each image in very large database is a very
time consuming process. It is also necessary to use unique keyword for annotation of each image,
so this is a very complex task. Text descriptions are sometimes incomplete because they cannot
depict complicated image features very well. Examples are texture images that cannot be

Content-based image retrieval (CBIR) systems were introduced to address the problems
associated with text-based image retrieval. To search and retrieve digital images CBIR uses
content of the images. Content-based means that the search analyses the contents of the image not
the metadata such as keywords or tags associated with the image. Here the term content means
colours, shapes, textures or any other information that derived from the image. In CBIR systems
input provide in terms of an image and based on image attribute matching the most similar
images from database are retrieved.
2. Related Work
Feature extraction is the main task in the CBIR systems to retrieve the similar images
from database. Similarity measurement decides how close a vector is to another vector.
Selection of similarity metrics has a direct impact on the performance of content-based
image retrieval. The type of feature vectors selected determines the type of measurement
that used to compare their similarity. Euclidean distance is the most common metric used
to measure the distance between two points in multi-dimensional space. To represent an
image, in feature extraction features such as colour, texture or shape from image are
extracted and creates a feature vector for each image.
2.1 Colour
Colour is one of the most important features visually recognized by humans in images. Colour
features are the most widely used in CBIR systems [10]. To extract the colour features from the
content of an image, a proper colour space and an effective colour feature extraction method are
required.
2.1.1 Colour space:
For a certain combination of a colour model plus a mapping function colour space is a more
specific term. The term colour space is used to identify colour models. Identifying a colour space
automatically identifies the associated colour model. The purpose of a colour space is to facilitate
the specification of colours. For different purposes many colour spaces, such as RGB, HSV,
CMYK and CIE L*a*b have been developed.
RGB: Computer can only identify the RGB colour component of an image. RGB has three colour
components: Red (R), Green (G) and Blue (B). RGB uses additive colour mixing. It describes
what kind of light needs to be emitted to produce a given colour. For red, green and blue
component RGB stores individual values. For representing colour images the RGB colour space
is most widely used systems, but it is not suitable for CBIR because it is a perceptually non-
uniform and device-dependent system.
CMYK: CMYK uses subtractive colour mixing and it describes what kind of inks needs to apply
so the light reflected from the substrate and through the inks produces a given colour. CIELAB:
The CIELAB (or L*a*b* or Lab) produce a colour space that is more perceptually linear than
other colour spaces. Linear means that a change of the same amount in a colour value should
produce a change of about the same visual importance.

HSV: To describe a specific colour the HSV colour space uses Hue (H), Saturation (S), and
brightness values (V). In interactive colour selection and manipulation this colour system is very
useful. It is easier to think about a colour in terms of hue and saturation than in terms of additive
or subtractive colour components. HSV is a transformation of an RGB colour space. Its
components are relative to the RGB colour space from which it derives. For human perceive HSV
space is more suitable.
After selecting a colour space effective colour descriptor required. To represent the colour of the
global or local areas colour descriptor needs. From various representation schemes several colour
descriptors have been developed such as colour histograms, colour moments, colour edge and
colour texture. Out of these colour histogram and colour moment are most commonly used
methods for the colour feature extraction.
2.1.2 Colour Histogram
Colour histogram is a method which is used to represent colour feature of an image. A colour
histogram is a type of bar graph. The height of each bar represents the amount of a particular
colour used in the image. The bars in a colour histogram are known as bins and they represent the
x-axis. On the number of colours in an image the number of bins are depend. Each bin contains
the number of pixels and it denotes y-axis which shows how many particular colour pixels an
image contains.
The colour histogram easily characterizes the global and local distribution of colours in an
image. In colour histograms quantization process is used [8]. Quantizing reduces the space
required to store the histogram information. Quantization reduces the information of the content
of images. Colour histogram has two types, global colour histogram (GCH) and local colour
histogram (LCH). A GCH takes colour histogram of the whole image and represents information
of an image; it does not consider colour distribution of regions in the image. In the LCH an image
divide into fixed blocks and takes the colour histogram of each of the blocks. LCH contains more
information about an image.
2.1.3 Colour moment:
In the method of colour moment, colour information focus on the low-level colour moment of the
image. For each colour component they calculate moment as first order, second-order and third-
order moment. These colour moment as first-order (mean) and second (variance) and third-order
(gradient), is very effective in colour distribution of images. Each pixel has three colour
components and each component has three low-order moments so there are nine colour
characteristics components. In the colour moment is only the initial colour characteristics
extraction of image is done and the effect of extraction is very rough.
2.2 Texture
Texture is the natural property of all surfaces, which describes visual patterns each having the
properties of homogeneity. A texture is characterized by intensity properties (tones) and spatial
relationships (structural). This is a feature that describes the distinctive physical composition of a
surface. The different texture properties as perceived by the human eye are, for example
regularity, directionality, smoothness, and coarseness. Image textures have useful applications in
4. International Journal of Computer-Aided Technologies (IJCAx) Vol.1,No.1,April 2014
24
image processing. They include: recognition of image regions using texture properties known as
texture classification [3], recognition of texture boundaries using texture properties known as
texture segmentation, texture synthesis, and generation of texture images from known texture
models. For all types of textures there is no any single method which gives best result [9]. The
commonly used methods for texture feature description are statistical, model-based and
transform-based methods. The texture feature description categories are explained below.
2.2.1 Statistical Methods
Statistical methods analyse the spatial distribution of grey values by computing local features at
each point in the image and derive set of statistics from the distribution of the local features. It
includes the methods such as co-occurrence matrix; statistical moments, autocorrelation function,
and grey level run lengths. The most commonly used statistical method is the Gray-level Co-
occurrence Matrix (GLCM). It is a two-dimensional matrix of pairs of pixels which are separated
by a distance in a given particular direction. It is popular in texture description and is based on the
repeated occurrence of some grey level configuration in the texture. Gray-level co-occurrence
matrix method of representing texture features has found useful applications in recognizing fabric
defects [8], and in rock texture classification and retrieval.
2.2.2 Model Based Approaches
Model-based texture methods capture the process that generated the texture. In the model-based
features, some part of the image model is assumed and estimation algorithm is used to set the
parameters of the model. There are three major model based methods: Markov random fields,
fractals, and the multi-resolution autoregressive features.
2.2.3 Transform Domain Features
There are several texture classifications using transform domain features such as discrete wavelet
transforms, Fourier transform and Gabor wavelets. Transform methods analyse the frequency
content of the image to determine texture features Wavelet analysis breaks up a signal into shifted
and scaled versions of the original wavelet and which refers to decomposition of a signal into a
family of basis functions obtained through translation and dilation of a special function. Moments
of wavelet coefficients in various frequency bands are effective for representing texture.
2.3 Shape
The shape of an object is the characteristic surface configuration as represented by the outline.
Shape recognition is one of the modes through which human perception of the environment is
executed. It is important in CBIR because it corresponds to region of interests in images.
Boundary-based and region-based are two types for the shape feature representations. In region
based techniques all the pixels within a shape are taken into consideration to obtain the shape
representation. Common region based methods use moment descriptors to describe shapes.
Instead of providing information just at a single point moments combine information across an
entire object. They capture some of the global properties which are missing from contour-based
representations. Contour based shape representation is more popular than the region based shape
5. International Journal of Computer-Aided Technologies (IJCAx) Vol.1,No.1,April 2014
25
representation. Simple contour-based shape descriptors include area, perimeter, compactness,
eccentricity and orientation. Complex boundary-based descriptors include Fourier descriptors,
grid descriptors, and chain codes.
2.3.1 Zernike moments (ZM)
The complex Zernike moments are derived from orthogonal Zernike polynomials so that Zernike
Moment is known as orthogonal moments. Zernike polynomials are the complete set of complex
valued functions. Zernike moments are invariant to the rotation and they are robust to noise. They
have minimum information redundancy because they based on orthogonal. But, there are some
problems with Zernike moments such as the continuous integrals approximated by discrete
summations. This approximation responsible for numerical errors in the computed moments and
affects the rotational invariance.
2.3.2 Eccentricity
The measure of aspect ratio is known as Eccentricity. It is simply ratio of the length of major axis
to the length of minor axis. There are two methods to calculate the eccentricity principal axes
method and minimum bounding rectangle method. Principal axes of a given shape defined as the
two segments of lines that cross each other orthogonally in the centres of the shape and represent
the directions with zero cross-correlation. Minimum bounding rectangle is the smallest rectangle
which contains every point in the shape so that it known as minimum bounding box. For arbitrary
shape eccentricity is calculated as the ratio of length and width of minimum bounding rectangle
of the shape. Due to this a contour is look as an instance from a statistical distribution.
3. Techniques of CBIR
In the CBIR features are most important content for indexing and retrieval of the image. Colour,
Shape and Texture are most important features of image. The feature extracted are then form a
vector and this vector will be used for indexing of particular image.
3.1 Colour & Texture Features for CBIR:
Biragle and Doye focus on colour and texture features for content based image retrieval [7]. For
improved retrieval performance they use the decomposition scheme based on colour planes in
combination with histogram. For each plane three level decomposition performed. Each image
divided into non-overlapping sub images and analysed using standard wavelet and histogram.
Standard Wavelets used for texture feature extraction and colour histogram for colour feature
extraction.
To create the feature vector first level energy and computed standard deviation of each sub-band
is used. Then to find similarity between images Euclidean distance metric is used. The average
percent retrieval efficiency using this method is up to 75%. The main advantage of three-colour
plane wavelet decomposition is that it yields a large number of sub bands and which improves
the retrieval accuracy.

3.2 CBIR using colour, texture & shape feature:
Hiremath and Pujari presents a framework for combining information of three features such as
colour, texture and shape information to achieve high retrieval efficiency [6]. The purpose of this
method is to capture local colour and texture descriptors in a segmentation framework of grids
and shape describable in terms of invariant moments computed on the edge image. In this
method, an image is partitioned into non overlapping tiles. These tiles are local colour and texture
descriptors for the image. This grid framework is extended across resolutions to capture different
image details within the same size tiles. A matching procedure based on an adjacency matrix of a
bipartite graph. For the query image and the target image tiles bipartite graph is built. The
labelled edges of the bipartite graph indicate the distances between tiles.
Image similarity computation based on most similar highest priority (MSHP) principle. In this
method first and second order statistical moments of Gabor filter used to extract the texture
feature, colour moment used for the colour feature extraction and Gradient vector flow
fields(GVF) are used to extract the shape of the object. In per resolution 52 features are computed
for every image tile. This method allows to tile from query image is matched to any tile in the
target image. The main advantage of this method is that it creates robust feature set for image
retrieval.
3.3. CBIR Using Feature Combination & Relevance Feedback (RF):
Zhao and Tang, Perform CBIR Using Optimal Feature Combination and RF [4]. In this approach
the comparison of the retrieval performance using different combinations of features is done. The
combination is done in two levels. One is the combination of colour and texture features and the
other is the combination of two textures extracted by two different texture feature extraction
methods. By comparing different combinations of visual features they choose optimal
combination of Gabor and wavelet transform texture features with the colour moment colour
feature which has a better retrieval performance. Retrieval is based on the similarity of visual
features combination of query image and for the similarity measurement Euclidian distance
method used.
From the retrieval result user selects the relevant images and the irrelevant images. This feedback
is provided as training set to the Support Vector Machine (SVM) classifier to train the SVM [5].
This approach focus on to minimize the gap between low-level features representation of images
and the user's high-level semantic concepts, for that it uses SVM based on RF(Relevance
Feedback) to learn user's query concepts [6]. SVM and feature similarity based relevance
feedback using best feature combination improves the retrieval precision. As number of feedback
increases the retrieval accuracy improves correspondingly. But in the relevance feedback for the
same output different users have different views about the similarity. So it becomes complex
process.
3.4. Semantic Image Retrieval by combining three Features:
To overcome the disadvantage of relevance feedback Singh, Dubey, Dixit and Gupta
experimentally evaluated two phase method for the extraction of semantic information [2]. In the
first phase feature database of images is created. The feature database contains information about
the colour, shape and texture of the image. In the feature extraction colour histogram for the
7. International Journal of Computer-Aided Technologies (IJCAx) Vol.1,No.1,April 2014
27
colour feature, for the texture feature coarseness, contrast, energy and directionality used and for
the shape feature Zernike moments and edge used. Feature database is created and stored
according to the highest three values of the hue histogram to reduce the processing time and
reduce dataset.
In the second phase, images which are relevant to the query image are retrieved. Then on
reducing dataset feature matching is done and extracts similar images to the query image
considering colour, texture and shape feature individually. For each feature set of images are
obtained. Finally combine all the features which obtain in a set of images and retrieve images
which are semantically most similar to the query image.
This method retrieves images which are semantically similar with the query image and it
improves the precision and recall of the image retrieval system. It retrieves all the similar images
based on the each feature individually so there is a no chance of missing relevant images, this is
the main advantage of this method. This approach is time consuming cause in this approach
similarity matching applied two times first using each feature individually and then jointly and
image retrieval process to perform two times first image retrieve using each feature individually
and then from that images most similar images are retrieved.
3.5. CBIR using Multiple SVM’s Ensemble:
Yildizer, Balci, Hassan and Alhajj proposed efficient content-based image retrieval using
Multiple Support Vector Machines Ensemble [1]. The main purpose of this method is to find a
good similarity measure between images. Similar images belong to predefined classes with close
probabilities and to find the class probabilities this approach uses Support Vector Regression
(SVR) model. The main steps in this approach are first, Feature extraction: in this step before
feature extraction resize the images and transform images from RGB data space to another space.
After that Daubechies wavelet transformation applied several times to extract features from
images. Second, Feature reduction: SVR ensemble constructs for feature reduction. It creates new
low dimensional feature vectors in reduced size due to which distance calculation reduced. Third,
construct a new SVR model to find the class probability estimates of the test Images. Fourth,
Query phase: in this phase Euclidian distance measurement uses as distance measure and return
similar images having lowest distance.The main purpose of this CBIR technique is that to handle
large image databases and by reducing the dimensionality of the feature vectors reduce the cost of
distance measurements due to which the accuracy of the classifier increase. Average
classification accuracy of this approach is 62% and average precision is 64%.

5. Conclusion
In this paper we surveyed the field of content-based image retrieval, by presenting an overview of
the most important aspects of images. We compare various methods used in the CBIR techniques
using different feature extraction techniques. The Semantic Image Retrieval method reduce
dataset but in this method image retrieval perform two times so it becomes complex. CBIR uses
multiple SVM’s ensemble method narrow down search space and handle large image database
using SVM. In CBIR system SVM is also used for the classification images. It proves CBIR
using multiple SVM’s ensemble method has better performance than other methods. In future, we
expect more efficient method for image retrieval which has high retrieval accuracy and precision.
