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.
Density Driven Image Coding for Tumor Detection in mri ImageIOSRjournaljce
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.

A New Approach for Segmentation of Fused Images using Cluster based ThresholdingIDES Editor
This paper proposes the new segmentation technique
with cluster based method. In this, the multi source medical
images like MRI (Magnetic Resonance Imaging), CT

tomography) are fused and then segmented using cluster based
thresholding approach. The edge details of an image have
become an essential technique in clinical and researchoriented
applications. The more edge details of the fused image

clustering process is to partition a fused image coefficients
into a number of clusters having similar features. These
features are useful to generate the threshold value for further

A New Method for Indoor-outdoor Image Classification Using Color Correlated T...CSCJournals
In this paper a new method for indoor-outdoor image classification is presented; where the concept of Color Correlated Temperature is used to extract distinguishing features between the two classes. In this process, using Hue color component, each image is segmented into different color channels and color correlated temperature is calculated for each channel. These values are then incorporated to build the image feature vector. Besides color temperature values, the feature vector also holds information about the color formation of the image. In the classification phase, KNN classifier is used to classify images as indoor or outdoor. Two different datasets are used for test purposes; a collection of images gathered from the internet and a second dataset built by frame extraction from different video sequences from one video capturing device. High classification rate, compared to other state of the art methods shows the ability of the proposed method for indoor-outdoor image classification.
IMPROVEMENT OF BM3D ALGORITHM AND EMPLOYMENT TO SATELLITE AND CFA IMAGES DENO...ijistjournal
This paper proposes a new procedure in order to improve the performance of block matching and 3-D filtering (BM3D) image denoising algorithm. It is demonstrated that it is possible to achieve a better performance than that of BM3D algorithm in a variety of noise levels. This method changes BM3D algorithm parameter values according to noise level, removes prefiltering, which is used in high noise level; therefore Peak Signal-to-Noise Ratio (PSNR) and visual quality get improved, and BM3D complexities and processing time are reduced. This improved BM3D algorithm is extended and used to denoise satellite and color filter array (CFA) images. Output results show that the performance has upgraded in comparison with current methods of denoising satellite and CFA images. In this regard this algorithm is compared with Adaptive PCA algorithm, that has led to superior performance for denoising CFA images, on the subject of PSNR and visual quality. Also the processing time has decreased significantly.
Comparison of various Image Registration Techniques with the Proposed Hybrid ...idescitation
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

REGION CLASSIFICATION BASED IMAGE DENOISING USING SHEARLET AND WAVELET TRANSF...csandit
This paper proposes a neural network based region classification technique that classifies
regions in an image into two classes: textures and homogenous regions. The classification is
based on training a neural network with statistical parameters belonging to the regions of
interest. An application of this classification method is applied in image denoising by applying
different transforms to the two different classes. Texture is denoised by shearlets while
homogenous regions are denoised by wavelets. The denoised results show better performance
than either of the transforms applied independently. The proposed algorithm successfully
reduces the mean square error of the denoised result and provides perceptually good results.
Image fusion is an image enhancement approach for increasing the visual perception from two or more image into a single image. Each image is obtained from different object in focus. This process is now broadly used in various application of image processing such as medical imaging such as MRI, CT [18] and PET, remote sensing, satellite imaging, in design of intelligent robot etc. In this paper we have gone through the literature work done by the various researchers to obtain high quality improved image by combining important and desirable features from two or more images into a single image. Different image fusion rules, like maximum selection scheme, weighted average scheme and window based verification scheme are discussed. We also discuss about the image fusion techniques using DWT. Distinct blurred images are fused using DWT, SWT and using local correlation and their results are compared. The role of fusion in image enhancement is also taken into consideration. The results of different fusion technique are also compared, which are furnished in pictures and tables.
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.

Multilinear Kernel Mapping for Feature Dimension Reduction in Content Based M...ijma
In the process of content-based multimedia retrieval, multimedia information is processed in order to
obtain descriptive features. Descriptive representation of features, results in a huge feature count, which
results in processing overhead. To reduce this descriptive feature overhead, various approaches have been
used to dimensional reduction, among which PCA and LDA are the most used methods. However, these
methods do not reflect the significance of feature content in terms of inter-relation among all dataset
features. To achieve a dimension reduction based on histogram transformation, features with low
significance can be eliminated. In this paper, we propose a feature dimensional reduction approaches to
achieve the dimension reduction approach based on a multi-linear kernel (MLK) modeling. A benchmark
dataset for the experimental work is taken and the proposed work is observed to be improved in analysis in
comparison to the conventional system.

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

REGION CLASSIFICATION AND CHANGE DETECTION USING LANSAT-8 IMAGESADEIJ Journal
The change detection in remote sensing images remains an important and open problem for damage assessment. A new change detection method for LANSAT-8 images based on homogeneous pixel transformation (HPT) is proposed. Homogeneous Pixel Transformation transfers one image from its original feature space (e.g., gray space) to another feature space (e.g., spectral space) in pixel-level to make the pre-event images and post-event images to be represented in a common space or projection space for the convenience of change detection. HPT consists of two operations, i.e., forward transformation and backward transformation. In the forward transformation, each pixel of pre-event image in the first feature space is taken and will estimate its mapping pixel in the second space corresponding to post-event image based on the known unchanged pixels. A multi-value estimation method with the noise tolerance is produced to determine the mapping pixel using K-nearest neighbours technique. Once the mapping pixels of pre-event image are identified, the difference values between the mapping image and the post-event image can be directly generated. Then the similar work is done for backward transformation to combine the post-event image with the first space, and one more difference value for each pixel will be generated. Then, the two difference values are taken and combined to improve the robustness of detection with respect to the noise and heterogeneousness of images. (FRFCM) Fast and Robust Fuzzy C-means clustering algorithm is employed to divide the integrated difference values into two clusters- changed pixels and unchanged pixels. This detection results may contain few noisy regions as small error detections, and a spatial-neighbor based noise filter is developed to reduce the false alarms and missing detections. The experiments for change detection with real images of LANSAT-8 in Tuticorin between 2013-2019 are given to validate the percentage of the changed regions in the proposed method.

transform. This study is carried out for mammographic image classification. It is performed in three stages:
extraction of features characterizing the tissue areas then a dimension reduction was achieved by four
different methods of discrimination and finally the classification phase was carried. We have late compared
the performance of two classifiers KNN and decision tree.
Results show the classification accuracy in some cases has reached 100%. We also found that generally the
classification accuracy increases with the dimension but stabilizes after a certain value which is
approximately d=60.
Improved nonlocal means based on pre classification and invariant block matchingIAEME Publication
One of the most popular image denoising methods based on self-similarity is called nonlocal
means (NLM). Though it can achieve remarkable performance, this method has a few shortcomings,
e.g., the computationally expensive calculation of the similarity measure, and the lack of reliable
candidates for some non repetitive patches. In this paper, we propose to improve NLM by integrating
Gaussian blur, clustering, and row image weighted averaging into the NLM framework.
Experimental results show that the proposed technique can perform denoising better than the original
NLM both quantitatively and visually, especially when the noise level is high.
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.
Land Cover maps supply information about the physical material at the surface of the Earth (i.e. grass, trees, bare ground, asphalt, water, etc.). Usually they are 2D representations so to present variability of land covers about latitude and longitude or other type of earth coordinates. Possibility to link this variability to the terrain elevation is very useful because it permits to investigate probable correlations between the type of physical material at the surface and the relief. This paper is aimed to describe the approach to be followed to obtain 3D visualizations of land cover maps in GIS (Geographic Information System) environment. Particularly Corine Land Cover vector files concerning Campania Region (Italy) are considered: transformed raster files are overlapped to DEM (Digital Elevation Model) with adequate resolution and 3D visualizations of them are obtained using GIS tool. The resulting models are discussed in terms of their possible use to support scientific studies on Campania Land Cover.

Cervical cancer is the highest rate of incidence after breast cancer, gastric cancer, colorectal cancer, thyroid cancer among all malignant that occurs to females ; also it is the most prevalent cancer among female genital cancers. Manual cervical cancer diagnosis methods are costly and sometimes result inaccurate diagnosis caused by human error but machine assisted classification system can reduce financial costs and increase screening accuracy. In this research article, we have developed multi class cervical classification system by using Pap Smear Images according to the WHO descriptive Classification of Cervical Histology. Then, this system classifies the cell of the Pap Smear image into anyone of five types of the classes of normal cell, mild dysplasia, moderate dysplasia, severe dysplasia and carcinoma in situ (CIS) by using individual and Combining individual feature extraction method with the classification technique. In this paper three Feature Extraction methods were used: From that three, two were individual feature extraction method namely Enriched Rough Set Texton Co-Occurrence Matrix (ERSTCM) and Enriched Micro Structure Descriptor (EMSD) and the remained one was combining individual feature extraction method namely concatenated feature extraction method (CFE). The CFE method represents all the individual feature extraction methods of ERSTCM & EMSD features are combining together to one feature to assess their joint performance. Then these three feature extraction methods are tested over Fuzzy Logic based Hybrid Kernel Support Vector Machine (FL-HKSVM) Classifier. This Examination was conducted over a set of single cervical cell based pap smear images. The dataset contains five classes of images, with a total of 952 images. The distribution of number of images per class is not uniform. Then the performance was evaluated in both the individual and combining individual feature extraction method with the classification techniques by using the statistical parameters of sensitivity, specificity & accuracy. Hence the resultant values of the statistical parameters described in individual feature extraction method with the classification technique, proposed EMSD+FLHKSVM Classifier had given the better results than the other ERSTCM+FLHKSVM Classifier and combining individual feature extraction method with the classification technique described, proposed CFE+FLHKSVM Classifier had given the better results than other EMSD+FLHKSVM & ERSTCM+FLHKSVM classifiers.

Analysis of the Waveform of the Acoustic Emission Signal via Analogue Modulat...IOSRjournaljce
The acoustic emission (AE) technique is a non-destructive testing technique applied to pressurized rigid pipelines in order to identify metallurgical discontinuities. This study analyses the dynamic behavior of the propagation of discontinuities in cracks via AE, in the following propagation classes: no propagation (NP), stable propagation (SP), and unstable propagation (UP). The methodology involves applying the concept of modulation of analogue signals, which are used in signal transmission in telecommunications, for the development of a neural network in order to determine new parameters for the AE waveform. The classification of AE signals into propagation classes occurs, therefore, through the extraction of information related to the dynamics of AE signals, by means of the parameters of the analogue carriers of the modulations (in amplitude and in angle) that make up the AE signal. This set of parameters enables an efficient classification (average of 90%) through the identification of patterns from the AE signals in the classes for monitoring the state of the discontinuity, through the use of computational intelligence techniques (artificial neural networks and nonlinear classification).

Abstract: 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.
Index Term: Pattern recognition, orientation spectral resolution, wavelet transformation, spectral features
I. Introduction
Pattern recognition has remained an area of research from past a decade. With the emergence of new
technologies, information sharing has become more effective in distributed domain. For the information’s
exchange from one location to other, or to retrieve data from a large information data set, automated retrieval
systems are in greater demands. In various means of applications, information sharing, retrieval, and processing
is a common task. These tasks are limited with their usage and resources availability. In almost all processing
system, obtained information’s are very much dependent on the accuracy of data given to process. Generally the
processing data are taken as direct input or as retrieved information from a large dataset. Wherein direct inputs
from user are constraint to information knowledge, it is always used as a querying process. Based on the query
passed, mining algorithms were executed to retrieve the nearest Match information’s from a volumetric data set.
The accuracy of such process depends on the retrieval algorithm and the representative features. These
algorithms, are developed, modified and evaluated to improve the retrieval system performances. Towards the
application of wavelet transformation for feature description in CBIR system, various approaches were
developed in past. In [1] for the purpose of efficiently and effectively retrieving the desired images from a large
image database, the development of a user-friendly image retrieval system is developed. In this paper, a content
based image retrieval method based on the discrete wavelet transform (DWT) based on the superiority in multi
resolution analysis and spatial-frequency localization. An interactive user interface such that the users can adjust
the weights for each wavelet feature according to their expectations is developed. The effect of wavelet feature
selection is evaluated. In [2] a novel CBIR method is proposed by exploit the wavelets which represent the
visual feature. Haar and D4 wavelet to decompose color images into multilevel scale and wavelet coefficients,
with which image feature extraction and similarity match by means of F-norm theory is carried out. A
progressive image retrieval strategy to achieve flexible CBIR is also proposed. In [3] a discrete wavelet
transform with texture for content based image retrieval is proposed. This method uses a 2-D Discrete Wavelet
Transform for reducing the Dimensions of test image and trained images. Further gray level co-occurrence
matrix is applied for all test and trained images of LL components of level 2 decomposed images for extract the
texture feature of the images. In [4] a wavelet-based salient point extraction algorithm is proposed. The color
and texture information in the locations given by these points provides significantly improved results in terms of
retrieval accuracy, computational complexity and storage space of feature vectors as compared to the global
feature approaches. A performance comparison is done on various image transforms like Wavelet transform,
Fourier transform, Haar transform, Walsh-Hadamard transform and discrete cosine transform using a fuzzy
similarity measure is presented in [5,6]. It is seen that according to retrieval performance Wavelet transform
gives the best result among the other mentioned transforms. It has higher recall and precision values and higher
crossover point. In [7] an application system which implements a retrieval method which combines color and
texture feature for retrieval of images from large image databases is proposed. In this the process retrieve
images by using techniques like Wavelet decomposition, Color correlogram, Median Cut algorithm, and Color
Mean. For testing the final feature vectors of an input image with the database images a SVM (Support Vector
Machine) classifier is used. A similar modeling is observed in [8], where an image retrieval approach based on
color, texture feature is developed. Wavelet based approach is proposed to achieve the objective of feature
extraction and a classifier using K-nearest neighbors Algorithm (KNN) is developed to perform the pattern

recognition approach. These approaches improved the retrieval performances in various applications. In [9] a
Wavelet Transform based analysis method for Face Recognition is proposed. The choice of the Wavelet
transform in this setting is motivated by its insensitivity to large variation in light direction, face pose, and facial
expression. In a similar approach in [10] the illumination conditions that effect the automatic face recognition
process is focused. In this work, a multi-resolution feature extraction algorithm for face recognition is proposed
based on two-dimensional discrete wavelet transform (2D-DWT), which efficiently exploits the local spatial
variations in a face image. Wavelet coefficients corresponding to each local region residing inside those
horizontal bands are selected as features. In the selection of the dominant coefficients, a threshold criterion is
proposed, which drastically reduces the feature dimension.
II. Pattern Recognition
The image recovery systems are determined with generally the content features of the image named as
shape or texture, color recognition. In this paper information of color-based is taken as the referencing index and
using DWT method the spectral variation can be calculated. In input image information we can extract the
frequency resolution information very efficiently using DWT method. Where the resolution information was
passed as additional information for recovery in past, computational complexity increases because increasing
the feature count result. To achieve the objective of image retrieval, the operation is performed in two stages,
(i) training and
(ii) testing.
A Basic architecture for such a system is shown in figure 1.
Figure 1: Fundamental architecture of a content based image retrieval system
In training and testing the samples are pre-processed for resizing, filtration and data precision. The pre-
processing sample is further processes for feature extraction. In this stage image features are extracted namely
shape or texture, color recognition. In this paper information of color-based is taken as the referencing index and
using DWT method the spectral variation can be calculated. In input image information we can extract the
frequency resolution information very efficiently using DWT method. Where the resolution information was
passed as additional information for recovery in past, computational complexity increases because increasing
the feature count result.
III. Spectral Resolution Coding
In image and signal processing DWT place an important role, particularly in spectral-resolution
representation. In image processing system, it is very difficult to get the intensity of gray-level image pixels of
information directly. But using Spectral-resolution we can get the information of image easily. The 2D-DWT
can divide an image into four different sub-bands. Those sub-bands contain three detailed component sub-bands
and one average sub-band. Those three detail sub-bands components can represent different features for an
image. Wavelets a, b (x) are functions generated from mother wavelet by dilations and translations
a, b (x) = | a | -1/2
a
bx
(1)
In wavelet transform function f represents the wavelets superposition. Wavelet can be divided using
weighted coefficients, as an integral over a range a and b of (x). In a spectral resolution analysis, a scaling
function (x) is employed to process the Spectral-resolution. The wavelet can be divided into a m,n(f ) called as
approximate coefficients of a m-1,l and c m,n(f ) termed as detail coefficients of a m-1,l using a low-pass and a high-
pass filter in cascade. The 2D decomposition is out by the combination of two 1D decomposition of WT. The
1D-DWT dividing an input signal x={x0, x1, …….,xn-1} into a high-pass sub-band c={c0, c1, …….. ,cn/2-1} and a low-
pass sub-band a={a0, a1, …….., an/2-1}. Those can be represented as,

𝐴 𝑛 = 2𝑛−𝑘 𝑥 𝑘𝑘 (2)
𝐶𝑛 = 𝑔2𝑛−𝑘 𝑥 𝑘𝑘 (3)
Where gn and hn are the high-pass and low-pass filter coefficients respectively.
Figure 2: 1-D DWT Decomposition
Figure 2 shows the recognition of a 1D-DWT filter banks for dividing of original into detail sub-band
coefficients respectively. The original image can be extracts the filter bank into two components one is high
components and another is low components. In a 2D-DWT can be comes from the two 1D-DWT of rows and
columns operations. Using 1D-DWT firstly done the row operation, on high –pass sub-band(H) and one low-
pass sub-band (L) as shown in figure 3. The 1D-DWT image is again transformed column operation is done to
get the four sub-bands by using another 1D-DWT. Figure 3 shows the 2D-DWT filter bank decomposition
operation. The LL sub-band represents the average component and LH, HL and HH sub-bands represents the
detail components.
Figure 3: Dimensional DWT Decomposition
There are many ways to divide a signal into various sub-bands in wavelet transforms. These contain
octave-band decomposition, wavelet-packet or adaptive decomposition and uniform decomposition. Octave-
band decomposition is mostly used.
IV. Orientation Spectral Resolution Coding
An integrated model for selective coding in image coding is developed. The block diagram represented below in
figure 4 gives the pictorial description of the proposed orientation filtering based image coding scheme.
Figure 4: Proposed Orientation Spectral resolution coding for image compression
Using directional density evaluator we can extract the 2D image features easily, which is most
preferable in image analysis. Using DDE we can get the total number of sub bands’ coefficients is the same as
that of the original image is called maximally decimated (MD) and reconstructed the original image without any
error is called perfect reconstruction (PR). Using tree structure three levels of two-band system can be
implemented in DDE. By using ploy-phase filter implemented each and every level, which construct the
structure very efficient computationally as well as extremely. DDE (directional density evaluator) divides the
frequency space into wedge-shaped as shown in fig.5.

Figure 5: Directional density evaluator frequency partitioning using 8 directions
In this 8 directions were used, where sub-bands directional of 1,2,3, and 4 indicates the directions
between -45° and +45° (horizontal directions) and 5,6,7 and 8 indicates the directions between 45° and135°
(vertical directions). To get the objective selection of coefficient for embedding, the output of WT are processed
with directional density evaluator and each band of 8-orientation is done. Rather than taking whole bands taking
only lower coefficient from each band and select the embedding locations. To realize the DDE, quincunx filter
banks are used. The filter arrangement is shown in fig.6.
Figure 6: Quincunx filter bank architecture
QFB (Quincunx filter bank) is applied at the 1st
level. The sampling matrix of quincunx id denoted by, 𝑄 =
1 −1
1 1
. The filtration is further divided by using two quincunx filter banks for the o/p’s y0 and y1. As a result
four directions will get the four outputs. These four directional outputs are represented by y00, y01, y10 and y11.
The quincunx filter banks of higher level results are shown in conjunction with re-sampling metrics. The re-
sampling coefficients used per horizontal and vertical directions as shown in below,
𝑅ℎ =
1 1
0 1
and𝑅 𝑣 =
1 0
−1 1
(4)
Each and every band apply sampling matrix and done the orientations, 8-orintations in results as y0 to y8. For
each of this directional band a normalized magnitude value is computed defined by,
𝑁 = ||𝑦𝑖,𝑗 ||2
, for i,j∈ 0,1 (5)
The band density having higher pixel density in such directions is kept unmodified and band having
lower normalized values are discarded from coding. As these are made on the directional band density hence the
image are least effected on the orientation variations. For this purpose the normalized magnitudes of all
directional bands are compared with a normalized threshold value given in (2). The Coefficients satisfying the
thresholding based criterion 𝑁 = ||𝑦𝑖,𝑗
2
> 𝑡 are only used for coding, the threshold (𝑡ℎ), is defined by,
𝑡 =
1
3
[ .𝑚
𝑖=1 .𝑛
𝑗 =1 𝑥𝑖,𝑗 ]
1
𝑚𝑥𝑛
(6)
The process of thresholding results in selection of effective oriented coefficients in each band and
finally the obtained normalized magnitudes in all directional bands are passed to code for compression. Wherein
the selective process reduces the coefficients having similarity in orientation, the reflecting visualization is not
degraded due to psycho visual redundancy. Taking these orientations as feature vectors a recognition system is
evaluated.

V. Experimental Results
Columbia Object Image Library (COIL-100) is a database of color images of 100 objects. The objects
were placed on a motorized turntable against a black background. The turntable was rotated through 360 degrees
to vary object pose with respect to a fixed color camera. Images of the objects were taken at pose intervals of 5
degrees. This corresponds to 72 poses per object. The images were size normalized. COIL-100 is available
online via ftp. i 1 Introduction We have constructed a database of 7,200 color images of 100 objects (72 images
per object). The objects have a wide variety of complex geometric and reflectance characteristics (see figure 7.
The database, called Columbia Object Image Library (COIL-100), was used in a real-time 100 object
recognition.

To evaluate the process of orientation Spectral resolution coding feature processing a test sample with
different orientation is passed to the developed system. The obtained observations for the developed system is as
illustrated below,
a) Sample I: Sample with 00

A selected test sample for the recognition process is shown in figure 8. This sample is passed for
feature extraction using Gray-Level Co-Occurrence Matrix (GLCM) based feature extraction and orientation

The top retrieved sample from the data base after classification for the two methods is shown in figure
10 (a) and (b) respectively. It is observed that the retrieval accuracy of the tow method is highest as the samples
are with no orientation effect. This test sample is then evaluated over different orientation and the obtained
results are as illustrated below;
b) Sample II: Sample with 150
orientation
Figure 11: Test sample at orientation of 150
The test sample is oriented by 150
orientations, and passed as a test sample to the developed system.
The features are extracted using conventional GLCM features and OSRC features. Using theses extracted
features, recognition process is carried out. The obtained results of the classified observations are illustrated in
figure 12.

Figure 12: Top 4 classified sample using (a) OSRC (b) GLCM at 150
orientations
When applied with orientation it is observed that the features extracted from the OSRC, in addition to
the shape information, depth feature is considered, this feature reveals the orientation information, and hence
these features variations are more contributive to the recognition process. However this variation is retained in
GLCM as no orientation effect is recorded in such approach. Hence the classification process leads to
misclassification process.

The test result for the given test sample. Illustrates a retrieval accuracy of 9/10, for the given test
sample. To evaluate the performance of proposed approach, one more numerical parameter, True Positive Factor
(TPF) and False Positive Factor (FPF) used. TPF is defined as the ratio of the number of truly classified samples
over the total available data samples. It finds the number of query samples classified truly according to their
labels. FPF is defined as number of falsely classified samples over the total available data samples. FPF finds
the number of samples that are classified wrongly. Mathematically, TPF and FPF can be expressed as
𝑇𝑃𝐹 =

For the proposed work,
Total samples available in dataset = 100.
Samples taken for testing = 30.
Number of truly classified samples = 29.
Number of falsely classified samples = 1.
The table shown below describes the TPF and FPF performance of the proposed and earlier approaches.

A generalized plot for the above observation was created and shown in fig.16. The lot was drawn between FPF
and TPF, also can be called ROC plot.
Fig.16: ROC analysis
The above figure represents the ROC curve for proposed approach and earlier approaches. The
proposed approach was carried out under various tests by varying number of testing samples and FPF and the
obtained results are shown in the fig.17.Form the above figure, as the FPF is increasing, the TPF is also
increasing. The increment in the FPF shows the probability of getting false results. The increment if TPF
denotes the probability of getting true results.
VI. Conclusion
A new approach to feature representation, based on spectral orientation, in the spectral band
decomposition is illustrated. The approach results in extraction of feature elements which are more effective in
descriptive representation, as compared to conventional wavelet based approach. The coding approaches,
extracts the non redundant feature coefficients as the descriptive elements, and hence are more finer in
representation. This results in improvement to accuracy in pattern recognition and hence lead to a more accurate
recognition system in image retrieval system.
