Wavelet-Based Color Histogram on Content-Based Image RetrievalTELKOMNIKA JOURNAL
The growth of image databases in many domains, including fashion, biometric, graphic design,
architecture, etc. has increased rapidly. Content Based Image Retrieval System (CBIR) is a technique used
for finding relevant images from those huge and unannotated image databases based on low-level features
of the query images. In this study, an attempt to employ 2nd level Wavelet Based Color Histogram (WBCH)
on a CBIR system is proposed. Image database used in this study are taken from Wang’s image database
containing 1000 color images. The experiment results show that 2nd level WBCH gives better precision
(0.777) than the other methods, including 1st level WBCH, Color Histogram, Color Co-occurrence Matrix,
and Wavelet texture feature. It can be concluded that the 2nd Level of WBCH can be applied to CBIR system.

Multi Resolution features of Content Based Image RetrievalIDES Editor
Many content based retrieval systems have been
proposed to manage and retrieve images on the basis of their
content. In this paper we proposed Color Histogram, Discrete
Wavelet Transform and Complex Wavelet Transform
techniques for efficient image retrieval from huge database.
Color Histogram technique is based on exact matching of
histogram of query image and database. Discrete Wavelet
transform technique retrieves images based on computation
of wavelet coefficients of subbands. Complex Wavelet
Transform technique includes computation of real and
imaginary part to extract the details from texture. The
proposed method is tested on COREL1000 database and
retrieval results have demonstrated a significant improvement
in precision and recall.
The development of multimedia system technology in Content based Image Retrieval (CBIR) System is
one in every of the outstanding area to retrieve the images from an oversized collection of database. The feature
vectors of the query image are compared with feature vectors of the database images to get matching images.It is
much observed that anyone algorithm isn't beneficial in extracting all differing kinds of natural images. Thus an
intensive analysis of certain color, texture and shape extraction techniques are allotted to spot an efficient CBIR
technique that suits for a selected sort of images. The Extraction of an image includes feature description and
feature extraction. During this paper, we tend to projected Color Layout Descriptor (CLD), grey Level Co-
Occurrences Matrix (GLCM), Marker-Controlled Watershed Segmentation feature extraction technique that
extract the matching image based on the similarity of Color, Texture and shape within the database. For
performance analysis, the image retrieval timing results of the projected technique is calculated and compared
with every of the individual feature.

Novel Approach for Image Restoration and TransmissionCSCJournals
This paper develops a new technique in image restoration and transmission process, where the image size is halved after transforming it to the frequency domain by applying discrete Fourier transform. The conjugate symmetry and mirror property of transformed image spectrums could be utilized by deleting the redundant spectrums from second half image after tracking and keeping the conjugated locations. Those redundant locations are kept using one- to- one relationship. Depending on the halving procedure, the new image size will be divided by two. A reconstructed procedure is created to redistribute the deleted spectrum with their associated locations. The reconstructed image is ready now for restoring again by applying the inverse discrete Fourier transform back to the spatial domain. The restored image is qualified using Peak Signal to Noise Ratio measurement and the result was very satisfied. The advantages of this technique appear in the storage cost, where the memory locations will be reduced to the half. Also, from communication side, this work approved that the image transmission time needs to transmit the halved image is half of the original one.

WEB IMAGE RETRIEVAL USING CLUSTERING APPROACHEScscpconf
Image retrieval system is an active area to propose a new approach to retrieve images from the
large image database. In this concerned, we proposed an algorithm to represent images using
divisive based and partitioned based clustering approaches. The HSV color component and Haar wavelet transform is used to extract image features. These features are taken to segment an image to obtain objects. For segmenting an image, we used modified k-means clustering algorithm to group similar pixel together into K groups with cluster centers. To modify Kmeans, we proposed a divisive based clustering algorithm to determine the number of cluster and get back with number of cluster to k-means to obtain significant object groups. In addition, we also discussed the similarity distance measure using threshold value and object uniqueness to quantify the results.
Sub-windowed laser speckle image velocimetry by fast fourier transform technique
Abstract
In this work, laser speckle velocimetry, a unique optical method for velocity measurement of fluid flow has been described. A laser sheet is developed and is illuminated on microscopic seeded particles to produce the speckle pattern at the recording plane. Double frame- single-exposure speckle images are captured in such a way that the second speckle image is shifted exactly in a known direction. The auto-correlation method has the ambiguity of direction of flow. To rectify this, spatial shift of the second image has been premeditated. Cross-correlation of sub interrogation areas is obtained by Fast Fourier Transform technique. Four sub-windows processed to obtain the velocity information with vector map analysis precisely.

Orientation Spectral Resolution Coding for Pattern RecognitionIOSRjournaljce
In the approach of pattern recognition, feature descriptions are of greater importance. Features are represented in spatial domain and transformed domain. Wherein, spatial domain features are of lower representation, transformed domains are finer and more informative. In the transformed domain representation, features are represented using spectral coding using advanced transformation technique such as wavelet transformation. However, the feature extraction approach considers the band coefficients; the orientation variation is not considered. In this paper towards inherent orientation variation among each spectral band is derived, and the approach of orientation filtration is made for effective feature representation. The obtained result illustrates an improvement in the recognition accuracy, in comparison to conventional retrieval system.

Image Registration is termed as the method to
transform different forms of image data into one coordinate
system. Registration is a important part in image processing
which is used for matching the pictures which are obtained at
different time intervals or from various sensors. A broad range
of registration techniques have been developed for the various
types of image data. These techniques are independently
studied for many applications resulting in the large body of
result. Vision is the most advanced of human sensors, so
naturally images play one of the most important roles in
human perception. Image registration is one of the branches
encompassed by the diverse field of digital image processing.
Due to its importance in many application areas as well as
since its nature is complicated; image registration is now the
topic of much recent research. Registration algorithms tend
to compute transformations to set correspondence betweenthe two images. In this paper the survey is done on various
image registration techniques. Also the different techniques

Spectral Density Oriented Feature Coding For Pattern Recognition ApplicationIJERDJOURNAL
ABSTRACT:- The significant of multi spectral band resolution is explored towards selection of feature coefficients based on its energy density. Toward the feature representiaon in transformed domain, multi wavelet transformations were used for finer spectral representation. However, due to a large feature count these features are not optimal under low resource computing system. In the recognition units, running with low resources a new coding approach of feature selection, considering the band spectral density is developed. The effective selection of feature element, based on its spectral density achieve two objective of pattern recognition, the feature coefficient representiaon is minimized, hence leading to lower resource requirement, and dominant feature representation, resulting in higher retrieval performance.
In this paper, we analyze and compare the performance of fusion methods based on four different
transforms: i) wavelet transform, ii) curvelet transform, iii) contourlet transform and iv) nonsubsampled
contourlet transform. Fusion framework and scheme are explained in detail, and two different sets of
images are used in our experiments. Furthermore, eight different performancemetrics are adopted to
comparatively analyze the fusion results. The comparison results show that the nonsubsampled contourlet
transform method performs better than the other three methods, both spatially and spectrally. We also
observed from additional experiments that the decomposition level of 3 offered the best fusion performance,
anddecomposition levels beyond level-3 did not significantly improve the fusion results.
A novel approach to Image Fusion using combination of Wavelet Transform and C...IJSRD
Panchromatic furthermore multi-spectral image fusion outstands common methods of high-resolution color image amalgamation. In digital image reconstruction, image fusion is standout pre-processing step that aims increasing hotspot image quality to extricate all suitable information from source images ruining inconsistencies or artifacts. Around the different strategies available for image fusion, Wavelet and Curvelet based algorithms are mostly preferred. Wavelet transform is useful for point singularities while Curvelet transform, as the name describes, is more useful for the analysis of images having curved shape edges. This paper reveals a study of development in the field of image fusion.

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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Abstract: Efficient, texture representation is important, in search and retrieval of similar texture patterns from
a large image database. There has been research on texture feature extraction by finding the Spatial/frequency
distribution of the patterns with tools like the Gabor filters, Pyramid-structured wavelet transform, and Multi
wavelet transform. In this paper, content based image retrieval method is used, to retrieve the images from the
database according to their similarity to the Query image. The aim of this project is to retrieve the images using
multi wavelet. Firstly, we calculate the multi wavelet of all images in database.secondly, to calculate the energy
and then distance between query and database images.
Keywords: Retrieving Images, CBIR (Content Based Image Retrieval) system, distance and energy
I. Introduction
Content-Based Image Retrieval (CBIR) is the process of retrieving images from a database on the basis
of features that are extracted automatically from the images themselves [2]. A CBIR method typically converts
an image into a feature vector representation and matches with the images in the database to find out the most
similar images. In the last few years, several research groups have been investigating content based
image retrieval. A popular approach is querying by example and computing relevance based on visual
similarity using low-level image features like color histograms, textures and shapes. Text-based image
retrieval can be traced back to the 1970’s; images were represented by textual descriptions and subsequently
retrieved using a text-based database management system [3]. Content-based image retrieval utilizes
representations of features that are automatically extracted from the images themselves. Most of the current
CBIR systems allow for querying-by-example, a technique wherein an image (or part of an image) is selected by
the user as the query. The system extracts the features of the query image, searches through the database for
images with similar features, and displays relevant images to the user in order of similarity to the query
[6][7][8][9].
Image Retrieval aims to provide an effective and efficient tool for managing large image databases.
With the ever growing volume of digital image generated, stored, accessed and analyzed.
The paper is organized as follows. Gabor wavelet is presented in Section II. Section III describes the Multi
wavelet. The texture feature calculation is presented in Section IV. Distance calculation are made in Section V.
Results are shown in section VI. Section VII describes the conclusion.
II. Gabor Wavelet
The Fourier transform has been the most commonly used tool for analyzing frequency properties of a
given signal, while after transformation, the information about time is lost and it’s hard to tell where a certain
frequency occurs. To solve this problem, we can use kinds of time-frequency analysis techniques. The Gabor
transform, named after Dennis Gabor, is a special case of the transform. It is used to determine
the sinusoidal frequency and phase content of local sections of a signal as it changes over time. The function to
be transformed is first multiplied by a Gaussian function, which can be regarded as a window function, and the
resulting function is then transformed with a Fourier transform to derive the time-frequency analysis. The
window function means that the signal near the time being analyzed will have higher weight. The Gabor
transform of a signal x(t) is defined by this formula:
(1)
The Gaussian function has infinite range and it is impractical for implementation. However, a level of
significance can be chosen (for instance 0.00001) for the distribution of the Gaussian function.
(2)
2. Multi Wavelet For Image Retrival Based On Using Texture And Color Querys

Outside these limits of integration , the Gaussian function is small enough to be ignored. Thus
the Gabor transform can be satisfactorily approximated as
(3)
Drawbacks
1) In this technique takes more execution time
2) The accuracy of similarity image retrieval is low.
To solve this problem using multi wavelet technique.
III. Multi Wavelet Transform
Multiwavelets were defined using several wavelets with several scaling functions [7]. Multiwavelets
have several advantages in comparison with scalar wavelet [8]. A scalar wavelet cannot possess all these
properties at the same time. On the other hand, a multiwavelet system can simultaneously provide perfect
representation while preserving length (Orthogonality), good performance at the boundaries (via linear-
phase symmetry), and a high order of approximation (vanishing moments) [9]. Thus multiwavelets offer
the possibility of superior performance and high degree of freedom for image processing applications,
compared with scalar wavelets.
During a single level of decomposition using a scalar wavelet transform, the 2- D image data is replaced by
four blocks corresponding to the sub bands representing either low pass or high pass in both
dimensions. These sub bands are illustrated inFig. 3.
The multi-wavelets used here have two channels, so there will be two sets of scaling coefficients and
two sets of wavelet coefficients. Since multiple iteration over the low pass data is desired, the scaling
coefficients for the two channels are stored together.
Likewise, the wavelet coefficients for the two channels are also stored together. The flow chart
of proposed method as shown in fig 1.

4) Calculate the features(color, texture and edge) values of the image
5) Similarity comparisons between input image and database by using Euclidian distance.
6) Sorting the distance values
7) Finally relevant images are retrieved with respect to corresponding query image I.
8) Repeat step 1 to 7 for another query image.
IV. Texture Feauture Calculation
For the texture characteristic four descriptors are used that are: contrast, entropy, energy and inverse
differential moment. We have used the Euclidian distance to measure the similarity between the Query image
and database image. First apply the Multi wavelet to get the image into eight sub-images.
Calculate the energy of all decomposed images at the same scale, using:
(4)
where M and N are the dimensions of the image, and X is the intensity of the pixel located at row i and
column j in the image map. Using the above algorithm, the energy levels of the sub-bands is calculated, and
further decomposition of the low-low sub-band image is also done This is repeated three times, to reach third
level decomposition. These energy level values are stored to be used in the Euclidean distance algorithm.
V. Distance Calculation
In this section, we take Canberra distance between two vectors p and q is shown below

In the experiment various images are used in the MATLAB program. The results of two different test
images using Gabor wavelet and multi wavelet as shown below.

VII. Conclusion
This paper attempts to evaluate the performance of the CBIR system on sample datasets of images
using Multi wavelet. Multi wavelet transform is the development of wavelet transform and construct wavelet
with two scaling function. Multi wavelet transform has many relatively good properties such as symmetry, short
support, orthogonality and high order vanishing moments. The system gives good results on the tests conducted.
Further tests must be conducted on various and large databases to have a more accurate evaluation. The
indexation technique is a crucial part in a CBIR system.
To have a more powerful and efficient retrieval system for image and multimedia databases, content
based queries must be combined with text and keyword predicates.
