In this paper the proposed system uses content based image retrieval (CBIR) technique for identification of seed e.g.
wheat, rice, gram etc. on the basis of their features. CBIR is a technique to identify or recognize the image on the basis of features
present in image. Basically features are classified in to four categories 1.color 2.Shape 3. texture 4. size .In this system we are
extracting color, shape feature extraction. After that classifying images in to categories using neural network according to the
weights and image displayed from the category for which neural network shows maximum weight. category1 belongs to wheat and
category2 belongs to gram. Experiment was conducted on 200 images of wheat and gram by using Euclidean distance(ED) and
artificial neural network techniques. From 200 images 150 are used for training purpose and 50 images are used for testing
purpose. The precision rate of the system by using ED is 84.4 percent By using Artificial neural network precision rate is 95
percent.
Image retrieval is the major innovations in the development of images. Mining of images is used to mine latest information from
the general collection of images. CBIR is the latest method in which our target images is to be extracted on the basis of specific features of
the specified image. The image can be retrieved in fast if it is clustered in an accurate and structured manner. In this paper, we have the
combined the theories of CBIR and analysis of features of CBIR systems.

A survey on full reference image quality assessment algorithmseSAT Journals
Abstract Image quality measurement is very important for various image processing applications such as recognition, retrieval, classification, compression, restoration and similar fields. The images may contain different types of distortions like blur, noise, contrast change etc. So it is essential to rate the image quality appropriately. Traditionally subjective rating methods are used to evaluate the quality of the image, in which humans rated the image quality based on time requirements. This is a costly process and it needs experts for evaluating image quality. Nowadays many image quality assessment algorithms are available for finding the quality of images. These are mainly based on the properties of human visual system. These image quality assessment algorithms are the objective methods for finding quality. Most of the methods are heuristic and limited to specific application environment. Whereas some methods perform efficiently and having comparable performance with the subjective ratings. Objective methods are easy for integrating into various image compression techniques and other image processing applications. Based on the availability of the image, image quality assessment algorithms are classified into full reference, reduced reference and no reference respectively. Full reference algorithms normally adopt a two stage structure including local quality measurement and pooling to get the quality value. The input for this two stage structure includes a reference image and a distorted image. This paper presents a survey on the existing image quality assessment algorithms based on full reference method, in which a reference image will be available for finding the quality of the distorted image.

The content based image retrieval (CBIR) technique
is one of the most popular and evolving research areas of the
digital image processing. The goal of CBIR is to extract visual
content like colour, texture or shape, of an image automatically.
This paper proposes an image retrieval method that uses colour
and texture for feature extraction. This system uses the query by
example model. The system allows user to choose the feature on
the basis of which retrieval will take place. For the retrieval
based on colour feature, RGB and HSV models are taken into
consideration. Whereas for texture the GLCM is used for
extracting the textural features which then goes into Vector
Quantization phase to speed up the retrieval process.

India is the second largest producer of wheat in the world after China. Specifying the quality of wheat manually requires an expert judgment and is time consuming. To overcome this problem, machine algorithms can be used to classify wheat according to its quality. In this paper we have done wheat classification by using two machine learning algorithms, that is, Support Vector Machine (OVR) and Neural Network (LM). For classification, images of wheat grain are captured using digital camera and thresholding is performed. Following this step, features of wheat are extracted from these images and machine learning algorithms are implemented. The accuracy of Support Vector Machine is 86.8% and of Neural network is 94.5%. Results show that Neural Network (LM)is better than Support Vector Machine(OVR).

Analysis of combined approaches of CBIR systems by clustering at varying prec...IJECEIAES
The image retrieving system is used to retrieve images from the image database. Two types of Image retrieval techniques are commonly used: content-based and text-based techniques. One of the well-known image retrieval techniques that extract the images in an unsupervised way, known as the cluster-based image retrieval technique. In this cluster-based image retrieval, all visual features of an image are combined to find a better retrieval rate and precisions. The objectives of the study were to develop a new model by combining the three traits i.e., color, shape, and texture of an image. The color-shape and colortexture models were compared to a threshold value with various precision levels. A union was formed of a newly developed model with a color-shape, and color-texture model to find the retrieval rate in terms of precisions of the image retrieval system. The results were experimented on on the COREL standard database and it was found that the union of three models gives better results than the image retrieval from the individual models. The newly developed model and the union of the given models also gives better results than the existing system named clusterbased retrieval of images by unsupervised learning (CLUE).

Text Mining in Digital Libraries using OKAPI BM25 ModelEditor IJCATR
The emergence of the internet has made vast amounts of information available and easily accessible online. As a result, most libraries have digitized their content in order to remain relevant to their users and to keep pace with the advancement of the internet. However, these digital libraries have been criticized for using inefficient information retrieval models that do not perform relevance ranking to the retrieved results. This paper proposed the use of OKAPI BM25 model in text mining so as means of improving relevance ranking of digital libraries. Okapi BM25 model was selected because it is a probability-based relevance ranking algorithm. A case study research was conducted and the model design was based on information retrieval processes. The performance of Boolean, vector space, and Okapi BM25 models was compared for data retrieval. Relevant ranked documents were retrieved and displayed at the OPAC framework search page. The results revealed that Okapi BM 25 outperformed Boolean model and Vector Space model. Therefore, this paper proposes the use of Okapi BM25 model to reward terms according to their relative frequencies in a document so as to improve the performance of text mining in digital libraries.

Policies for Green Computing and E-Waste in NigeriaEditor IJCATR
Computers today are an integral part of individuals’ lives all around the world, but unfortunately these devices are toxic to the environment given the materials used, their limited battery life and technological obsolescence. Individuals are concerned about the hazardous materials ever present in computers, even if the importance of various attributes differs, and that a more environment -friendly attitude can be obtained through exposure to educational materials. In this paper, we aim to delineate the problem of e-waste in Nigeria and highlight a series of measures and the advantage they herald for our country and propose a series of action steps to develop in these areas further. It is possible for Nigeria to have an immediate economic stimulus and job creation while moving quickly to abide by the requirements of climate change legislation and energy efficiency directives. The costs of implementing energy efficiency and renewable energy measures are minimal as they are not cash expenditures but rather investments paid back by future, continuous energy savings.

Most of the existing semantic similarity measures that use ontology structure as their primary source can measure semantic similarity between concepts/classes using single ontology. The ontology-based semantic similarity techniques such as structure-based semantic similarity techniques (Path Length Measure, Wu and Palmer’s Measure, and Leacock and Chodorow’s measure), information content-based similarity techniques (Resnik’s measure, Lin’s measure), and biomedical domain ontology techniques (Al-Mubaid and Nguyen’s measure (SimDist)) were evaluated relative to human experts’ ratings, and compared on sets of concepts using the ICD-10 “V1.0” terminology within the UMLS. The experimental results validate the efficiency of the SemDist technique in single ontology, and demonstrate that SemDist semantic similarity techniques, compared with the existing techniques, gives the best overall results of correlation with experts’ ratings.

A Strategy for Improving the Performance of Small Files in Openstack Swift Editor IJCATR
This is an effective way to improve the storage access performance of small files in Openstack Swift by adding an aggregate storage module. Because Swift will lead to too much disk operation when querying metadata, the transfer performance of plenty of small files is low. In this paper, we propose an aggregated storage strategy (ASS), and implement it in Swift. ASS comprises two parts which include merge storage and index storage. At the first stage, ASS arranges the write request queue in chronological order, and then stores objects in volumes. These volumes are large files that are stored in Swift actually. During the short encounter time, the object-to-volume mapping information is stored in Key-Value store at the second stage. The experimental results show that the ASS can effectively improve Swift's small file transfer performance.
Integrated System for Vehicle Clearance and RegistrationEditor IJCATR
Efficient management and control of government's cash resources rely on government banking arrangements. Nigeria, like many low income countries, employed fragmented systems in handling government receipts and payments. Later in 2016, Nigeria implemented a unified structure as recommended by the IMF, where all government funds are collected in one account would reduce borrowing costs, extend credit and improve government's fiscal policy among other benefits to government. This situation motivated us to embark on this research to design and implement an integrated system for vehicle clearance and registration. This system complies with the new Treasury Single Account policy to enable proper interaction and collaboration among five different level agencies (NCS, FRSC, SBIR, VIO and NPF) saddled with vehicular administration and activities in Nigeria. Since the system is web based, Object Oriented Hypermedia Design Methodology (OOHDM) is used. Tools such as Php, JavaScript, css, html, AJAX and other web development technologies were used. The result is a web based system that gives proper information about a vehicle starting from the exact date of importation to registration and renewal of licensing. Vehicle owner information, custom duty information, plate number registration details, etc. will also be efficiently retrieved from the system by any of the agencies without contacting the other agency at any point in time. Also number plate will no longer be the only means of vehicle identification as it is presently the case in Nigeria, because the unified system will automatically generate and assigned a Unique Vehicle Identification Pin Number (UVIPN) on payment of duty in the system to the vehicle and the UVIPN will be linked to the various agencies in the management information system.

Energy-Aware Routing in Wireless Sensor Network Using Modified Bi-Directional A*Editor IJCATR
Energy is a key component in the Wireless Sensor Network (WSN)[1]. The system will not be able to run according to its function without the availability of adequate power units. One of the characteristics of wireless sensor network is Limitation energy[2]. A lot of research has been done to develop strategies to overcome this problem. One of them is clustering technique. The popular clustering technique is Low Energy Adaptive Clustering Hierarchy (LEACH)[3]. In LEACH, clustering techniques are used to determine Cluster Head (CH), which will then be assigned to forward packets to Base Station (BS). In this research, we propose other clustering techniques, which utilize the Social Network Analysis approach theory of Betweeness Centrality (BC) which will then be implemented in the Setup phase. While in the Steady-State phase, one of the heuristic searching algorithms, Modified Bi-Directional A* (MBDA *) is implemented. The experiment was performed deploy 100 nodes statically in the 100x100 area, with one Base Station at coordinates (50,50). To find out the reliability of the system, the experiment to do in 5000 rounds. The performance of the designed routing protocol strategy will be tested based on network lifetime, throughput, and residual energy. The results show that BC-MBDA * is better than LEACH. This is influenced by the ways of working LEACH in determining the CH that is dynamic, which is always changing in every data transmission process. This will result in the use of energy, because they always doing any computation to determine CH in every transmission process. In contrast to BC-MBDA *, CH is statically determined, so it can decrease energy usage.

Hangul Recognition Using Support Vector MachineEditor IJCATR
The recognition of Hangul Image is more difficult compared with that of Latin. It could be recognized from the structural arrangement. Hangul is arranged from two dimensions while Latin is only from the left to the right. The current research creates a system to convert Hangul image into Latin text in order to use it as a learning material on reading Hangul. In general, image recognition system is divided into three steps. The first step is preprocessing, which includes binarization, segmentation through connected component-labeling method, and thinning with Zhang Suen to decrease some pattern information. The second is receiving the feature from every single image, whose identification process is done through chain code method. The third is recognizing the process using Support Vector Machine (SVM) with some kernels. It works through letter image and Hangul word recognition. It consists of 34 letters, each of which has 15 different patterns. The whole patterns are 510, divided into 3 data scenarios. The highest result achieved is 94,7% using SVM kernel polynomial and radial basis function. The level of recognition result is influenced by many trained data. Whilst the recognition process of Hangul word applies to the type 2 Hangul word with 6 different patterns. The difference of these patterns appears from the change of the font type. The chosen fonts for data training are such as Batang, Dotum, Gaeul, Gulim, Malgun Gothic. Arial Unicode MS is used to test the data. The lowest accuracy is achieved through the use of SVM kernel radial basis function, which is 69%. The same result, 72 %, is given by the SVM kernel linear and polynomial.

Abstract: : In this paper the proposed system uses content based image retrieval (CBIR) technique for identification of seed e.g.
wheat, rice, gram etc. on the basis of their features. CBIR is a technique to identify or recognize the image on the basis of features
present in image. Basically features are classified in to four categories 1.color 2.Shape 3. texture 4. size .In this system we are
extracting color, shape feature extraction. After that classifying images in to categories using neural network according to the
weights and image displayed from the category for which neural network shows maximum weight. category1 belongs to wheat and
category2 belongs to gram. Experiment was conducted on 200 images of wheat and gram by using Euclidean distance(ED) and
artificial neural network techniques. From 200 images 150 are used for training purpose and 50 images are used for testing
purpose. The precision rate of the system by using ED is 84.4 percent By using Artificial neural network precision rate is 95
percent.
Keywords: Features, Color, Shape, CBIR, Classification, ANN, Euclidean distance
1. INTRODUCTION
The application of machine vision is very important in
agricultural industry. Seed analysis and classification can
provide addaitional knowledge in their production, seeds
quality control and in impurities identification. Generally
these activities are performed by specialists by visually
inspecting each sample, which is a very tedious and time
consuming task [1]. So, automation is required in this field.
Now a day, computer vision technology is applied in a
large variety of fields to increase the efficiency of the work.
So, This paper uses machine vison technique for the
recognition aspect of the said problems[2].
In this paper a system is designed to recognize the different
types of grains by their images on the basis of their features
using content based image retrieval technique. Content-
based image retrieval is a technique which uses visual
contents to search images from large scale image databases
according to users' interests. CBIR technique is further
explained in next section. The proposed technique is based
on color and shape features. And for classification two
approaches are used and then compared. First classification
is done through Artificial Neural Network(ANN) and
second is done through finding the mininmum Euclidean
Distance between the features of two images.
2. CONTENT BASED IMAGE
RETRIEVAL
There are basically two types of image retrieval techniques
1.Text based image retrieval 2.Content based image
retrieval. In the text based image retrieval technique,
images are indexed on the basis of heading or topic,
description, keyword. Texture based images can not be
retrieved by text based query. To overcome this problem of
text based image retrieval and reducing human effort in
indexing process[3].
Content based image retrieval is a best technique to retrieve
an image because it reduces the image indexing and texture
based problems. efficiency of CBIR system can be
improved by providing the feedback for a particular image
which is not recognized by the system.
In a general CBIR system different types of features of
image database is calculated and feature database is
created. When the random test or input or query image is
given to the system then all the defined features is extracted
for that particular image and stored in feature vector.
2. International Journal of Computer Applications Technology and Research
Volume 2– Issue 2, 208 - 213, 2013
www.ijcat.com 209
Then image retrieval is done by comparing the similarity
between the query feature vector and different feature
vectors of feature database.
And then the image which has closest feature set as the
query image is displayed as the result. The general
architecture of CBIR system is shown in Fig 1[3].
3. RELATED WORK
There are many researchers who develop a variety of seed
image recognition system by applying different-different
classification techniques e.g. a artificial neural network, a
Euclidean distance technique, Histogram Intersection
Distance etc. The details of each technique given below-
3.1 Euclidean Distance Method
Benjamaporn Lurstwut and chomtip pornpanomchai
developed a method which uses shape ,size ,color , texture
feature extraction with the Euclidean distance technique to
classify seed Images. The system’s recognition rate was
95.1 % for trained dataset and 64.0 percent for unknown in
untrained dataset [4].
Dr. H.B.Kekre, Mr. Dhirendra Mishra, Ms. Stuti Narula
and Ms. Vidhi Shah applied the color feature extraction to
recognize different kinds of image. They applied Euclidean
distance technique with The different images of the same
class give results varied from 30% to 60% for a database
of size 300 [5].
Poulami Haldar and Joydeep Mukherjee used Euclidean
matrix method to calculate the distance vector. System
provides overall accuracy 87.50 % for the images of
different class [6].
3.2 Artificial Neural Network
Dayanand Savakar designed algorithms which is used to
extract 18 color and 27 texture features from food grains.
For the Recognition and Classification of Similar Looking
Food Grain Images this system uses artificial neural
network. Recognition of Mustard is about 87% and for
Soya is 78% using color feature and on the basis of texture
feature extraction maximum classification rate is 84% [7].
Ai-Guo OuYang, Rong-jie Gao, Yan-de Liu,,Xu-dong Sun,
Yuan-yuan Pan and Xiao-ling Dong designed a system in
which color features in RGB and color space is computed.
A back feed forward neural network trained to identify rice
seed 86.5 % rice seeds were identified by the system [8].
3.3 Histogram Intersection Distance
Manimala Singha and K.Hemachandran used histogram
intersection distance for feature similarity matching.
Experiment performed on standard “Wang Database”
containing 1000 image. In it texture and color feature
extracted through wavelet transformation and color
histogram [9].
3.4.Support vector machine
Ying Liua, Dengsheng Zhanga, Guojun Lua and Wei-Ying
Mab used SVM in their system because of SVM has been
used for object recognition, text classification, etc. After
using SVM in that system an improvement of 10% in

retrieval accuracy is obtained compared with SVM (400
images for training) with much fewer training data [10].
b) Kantip Kiratiratanapruk and Wasin Sinthupinyo classify
defects of corn seed in more than ten categories and
extracted color, texture feature. They used SVM as type
classifier. Accuracy of the system is 96.5 % for normal
seed type and 86.5 % in the case of defect seed(group)
types [1].
On the basis of above literature reviews it has been
observed that ANN and Euclidean distance method of
classification can provide better results with shape and
color features.
4. PROPOSED METHODOLOGY
The general methodology of the proposed system is shown
in Fig 2, which is further explained in subsections.
4.1 Image acquisition
12 mega pixel camera is used for taking the images of
wheat, gram and pulse. Distance between seed and camera
is almost equal to 14 centimeters.
4.2 Image preprocessing: Preprocessing
operation includes the following steps-
4.2.1 Image resizing: The input images captured by
different cameras may have different sizes which can affect
the result, so initial resizing is necessary.
4.2.2 RGB to Gray Scale Conversion: Equation 1 is
used to convert the RGB value of a pixel into its gray
value.
gray=.2989*R+.5870*G*.1140*B
4.2.3 Gray to Binary Image Conversion:
Binarization is done using otsu method, it can be done
using graythresh function in MATLAB.
4.2.4 Morphological Processing: Closing and
Filling operations are performed using a disk type
structuring elements of radius 2 to fill any holes in the
images.
The steps of pre-processing on an input of wheat is shown
in Fig 3.
4.3.Feature extraction
Following shape and color features are extracted for each
Input Image.
4.3.1 Shape feature extraction: Following shape
features are considered.
Seed roundness : Roundness of each seed is calculated w.r.t
circle, means when the value of roundness of any particular
seed is .9 then it’s almost round. Roundness can be
calculated by following equation.
R = 4*pi*area/P^2, where P is the perimeter of the seed.
4.3.2 Color feature extraction
Row mean and column mean: For each Red, Green and
Blue plane row and column mean is calculated by
following step.
a)Three color planes Red, Green ,Blue are separated and
step 2 to 4 is performed on each plane.

b) For each plane row mean and column mean of colors are
calculated.
Pictorially the row and column mean is calculated as
follows [5]:
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
c) The row mean of all three planes are stored as 3 new
features in feature vector.
Dominant color: Dominant Color is calculated for each
Red, Green and Blue Plane by their histogram.
Histogram is representation of the occurrence of relative
frequencies of various gray levels in an image. Dominant
color is that gray level which has the maximum occurrence
in the image. 3 more features are then added in the feature
vector.
Median: It can be used to determine the value of intensity
level of pixel which is separating high intensity value pixel
from low intensity value pixel. Three median values are
calculated for Red, Green and Blue Planes.
Some other statistical features are also calculated [11].
Standard Deviation: In the digital image processing it
shows variation from standard or expected value. It is
calculated for each plane by following function in
MATLAB.
std((std(Red,0,1))',0,1);
Covariance: It is a positive number.It is the measure of
change in two variable(random numbers) together.
diag(cov(diag(cov(Red)))')
Kurtosis: It tells about the shape of probability distribution
function of a random number.high curtosis value is good
for system because of ,it shows low noise and low
resolution.
kurtosis((kurtosis(Red))')
Skewness: The value of skewness can be positive, negative,
zero or may be undefined. Negative skewness shows that
more values lies to the right of the mean, positive skewness
means more values lies to the left of mean and zero
skewness shows values are evenly distributed on both side
of mean.
skewness((skewness(Red))')
Moment: The central first moment is zero and second
central moment is calculated by using a divisor of N
instead of N-1.
N -> length of vector or number of rows in matrix.
moment((moment(Red,3))',3)
4.4 Image Recognition
Image recognition is done using both ANN and Euclidean
distance method.
Euclidean Distance Method
In this method Euclidean distance is calculated between a
feature vector of test image and the feature file of all
sample images stored in the database. The Euclidean
distance can be calculated by using equation:
ED = ට∑ ሺܿെ ܾሻଶ
ୀଵ
Where ED is the Euclidean distance ,
m is number of features,
ܿ is the value of feature j stored in the predefined
database,
ܾ is the value of feature
Artificial neural network
A neural network, illustrated in Fig. 4, consists of units
(neurons), arranged in layers, which convert an input vector
into some output. Each unit takes an input, applies a (often
nonlinear) function to it and then passes the output on to
the next layer. Generally the networks are defined to be
feed-forward: a unit feeds its output to all the units on the
next layer, but there is no feedback to the previous layer.
Weightings are applied to the signals passing from one unit
to another, and it is these weightings which are tuned in the
training phase to adapt a neural network to the particular
problem at hand. This is the learning phase.

5. EXPERIMENTAL RESULTS
The system is developed using MATLAB (R2011a), i
system 200 samples images of three different grains are
taken by camera, from which 150 images are used for
training phase and 50 for testing phase. Then
features of 150 sample images are calculated

file stores features in a 25x150 array.
In classification using ANN method , first training of
network is done using the previously generated
"feature_file.mat" of 150 images , with 10 hidden neurons.
Final application gives an option to user to select a test
image form the rest 50 testing images and then the 25
features of this test image is calculated and stored in a
'test.mat' file, which is a 25x1 array. This "test.mat" file is
then passed to the trained network. It gives 95% accuracy.
Euclidean Distance methods outputs that image from
training set which has the closest features of test image. It
gives 84.4 % accuracy.
