An approach for underwater fish recognition based on wavelet transform is presented in this paper. This approach decomposes the input image into sub-bands by using the multi resolutional analysis known as Discrete Wavelet Transform (DWT). As each sub-band in the decomposed image contains useful information about the image, the mean values of every sub-band are assumed as features. This approach is tested on Underwater Photography - A Fish Database. The database contains 7953 pictures of 1458 different species. The database is considered for the classification based on Support Vector machine (SVM) classifier. The result shows that maximum recognition accuracy of 90.74% is achieved by the wavelet features.

Target Detection Using Multi Resolution Analysis for Camouflaged Images ijcisjournal
Target detection is a challenging problem having many applications in defense and civil. Most of the
targets in defense are camouflaged. It is difficult for a system to detect camouflaged targets in an image. A
novel and constructive approach is proposing to detect object in camouflage images. This method uses
various methodologies such as 2-D DWT, gray level co-occurrence matrix (GLCM), wavelet coefficient
features, region growing algorithm and canny edge detection. Target detection is achieved by calculating
wavelet coefficient features from GLCM of transformed sub blocks of the image. Seed block is obtained by
evaluating wavelet coefficient features. Finally the camouflage object is highlighted using image
processing schemes. The proposed target detection system is implemented in Matlab 7.7.0 and tested on
different kinds of images.

popular for browsing, searching and retrieving images in different fields including web based

however, is in designing a system that returns a set of relevant images i.e. if the query image
represents a horse then the first images returned from a large image dataset must return horse
images as first responses. In this paper, we have combined YACBIR [7], a CBIR that relies on
color, texture and points of interest and Multiple Support Vector Machines Ensemble to reduce
the existing gap between high-level semantic and low-level descriptors and enhance the
performance of retrieval by minimize the empirical classification error and maximize the
geometric margin classifiers. The experimental results show that the method proposed reaches

This paper focuses on no-reference image quality assessment(NR-IQA)metrics. In the literature, a wide range of algorithms are proposed to automatically estimate the perceived quality of visual data. However, most of them are not able to effectively quantify the various degradations and artifacts that the image may undergo. Thus, merging of diverse metrics operating in different information domains is hoped to yield better performances, which is the main theme of the proposed work. In particular, the metric proposed in this paper is based on three well-known NR-IQA objective metrics that depend on natural scene statistical attributes from three different domains to extract a vector of image features. Then, Singular Value Decomposition (SVD) based dominant eigenvectors method is used to select the most relevant image quality attributes. These latter are used as input to Relevance Vector Machine (RVM) to derive the overall quality index. Validation experiments are divided into two groups; in the first group, learning process (training and test phases) is applied on one single image quality database whereas in the second group of simulations, training and test phases are separated on two distinct datasets. Obtained results demonstrate that the proposed metric performs very well in terms of correlation, monotonicity and accuracy in both the two scenarios.

A Survey on the Analysis of Dissolved Oxygen Level in Water using Data Mining...IIRindia
Data Mining (DM) is a powerful and a new field having various techniques to analyses the recent real world problems. In DM, environmental mining is one of the essential and interesting research areas. DM enables to collect fundamental insights and knowledge from massive volume of environmental data. The water quality is determining the condition of water in the environment. It represents the concentration and state (dissolved or particulate) of some or all the organic and inorganic material present in the water, together with certain physical characteristics of the water. The Dissolved Oxygen (DO) is one of the important aspects of water quality. The DO is the quantity of gaseous oxygen (O2) incorporated into the water. The DO is essential for keeping the water organisms alive. The amount of DO level in the water can be detected by various methods. The data mining techniques are properly used to find DO Level in the different types of water. A number of DM methods used to analyze the DO level such as Multi-Layer Perceptron, Multivariate Linear Regression, Factor Analysis, and Feed Forward Neural Network. This survey work discusses about such type of methods, particularly used for the analysis of DO level elaborately.
Kidney Failure Due to Diabetics – Detection using Classification Algorithm in...IIRindia
In order to analyse the chosen data from various points of view, data mining is used as the effective process. This process is also used to sum-up all those views into useful information. There are several types of algorithms in data mining such as Classification algorithms, Regression, Segmentation algorithms, association algorithms, sequence analysis algorithms, etc.,. The classification algorithm can be used to bifurcate the data set from the given data set and foretell one or more discrete variables, based on the other attributes in the dataset. The ID3 (Iterative Dichotomiser 3) algorithm is an original data set S as the root node. An unutilised attribute of the data set S calculates the entropy H(S) (or Information gain IG (A)) of the attribute. Upon its selection, the attribute should have the smallest entropy (or largest information gain) value. The prime objective of this paper is to analyze the data from a Kidney disorder due to diabetics by using classification technique to predict class accurately.
Silhouette Threshold Based Text Clustering for Log AnalysisIIRindia
Automated log analysis has been a dominant subject area of interest to both industry and academics alike. The heterogeneous nature of system logs, the disparate sources of logs (Infrastructure, Networks, Databases and Applications) and their underlying structure & formats makes the challenge harder. In this paper I present the less frequently used document clustering techniques to dynamically organize real time log events (e.g. Errors, warnings) to specific categories that are pre-built from a corpus of log archives. This kind of syntactic log categorization can be exploited for automatic log monitoring, priority flagging and dynamic solution recommendation systems. I propose practical strategies to cluster and correlate high volume log archives and high velocity real time log events; both in terms of solution quality and computational efficiency. First I compare two traditional partitional document clustering approaches to categorize high dimensional log corpus. In order to select a suitable model for our problem, Entropy, Purity and Silhouette Index are used to evaluate these different learning approaches. Then I propose computationally efficient approaches to generate vector space model for the real time log events. Then to dynamically relate them to the categories from the corpus, I suggest the use of a combination of critical distance measure and least distance approach. In addition, I introduce and evaluate three different critical distance measures to ascertain if the real time event belongs to a totally new category that is unobserved in the corpus.
Analysis and Representation of Igbo Text Document for a Text-Based SystemIIRindia
The advancement in Information Technology (IT) has assisted in inculcating the three Nigeria major languages in text-based application such as text mining, information retrieval and natural language processing. The interest of this paper is the Igbo language, which uses compounding as a common type of word formation and as well has many vocabularies of compound words. The issues of collocation, word ordering and compounding play high role in Igbo language. The ambiguity in dealing with these compound words has made the representation of Igbo language text document very difficult because this cannot be addressed using the most common and standard approach of the Bag-Of-Words (BOW) model of text representation, which ignores the word order and relation. However, this cause for a concern and the need to develop an improved model to capture this situation. This paper presents the analysis of Igbo language text document, considering its compounding nature and describes its representation with the Word-based N-gram model to properly prepare it for any text-based application. The result shows that Bigram and Trigram n-gram text representation models provide more semantic information as well addresses the issues of compounding, word ordering and collocations which are the major language peculiarities in Igbo. They are likely to give better performance when used in any Igbo text-based system.

Abstract: An approach for underwater fish recognition
based on wavelet transform is presented in this paper.
This approach decomposes the input image into sub-
bands by using the multi resolutional analysis known as
Discrete Wavelet Transform (DWT). As each sub-band
in the decomposed image contains useful information
about the image, the mean values of every sub-band are
assumed as features. This approach is tested on
Underwater Photography - A Fish Database. The
database contains 7953 pictures of 1458 different species.
The database is considered for the classification based on
Support Vector machine (SVM) classifier. The result
shows that maximum recognition accuracy of 90.74% is
achieved by the wavelet features.
Keywords: Underwater fish recognition, wavelet
transform, Haar wavelet, SVM Classifier.
I. INTRODUCTION
A model that captures the contextual information from
more than a hundred object categories using a tree
structure is presented in [1]. A tree based context model
that improves the object recognition performance and
also provides a coherent interpretation that enables a
reliable image querying system by multiple object
categories. Group Sensitive Multiple Kernel Learning
(GSMKL) method for object recognition to
accommodate the intra-class diversity and the inter-class
correlation is presented in [2].
The distinct multicolored regions are detected using edge
maps and clustering. An illumination and rotation
invariant object recognition system is proposed in [3].
The color desriptions from distinct regions covering
multiple segments are considered for object
representation in [4]. A method used for the category of
object recognition by civilizing the popular methods from
the following two aspects is proposed in [5]. Models that
are used for capturing the contextual information among
the hundred object categories using a tree structure are
proposed in [6]. It uses objects that contain many
instances of different object categories.
A new video surveillance object recognition algorithm is
presented in [7], in which improved invariant moments
and length-width ratio of object are extracted as shape
feature. Bayesian approach of dynamically selecting
camera parameters to distinguish a given object from a
finite set of object classes is proposed in [8]. The
Gaussian process regression is applied to learn the
likelihood of image features given the object classes and
camera parameters.
II. PROPOSED SYSTEM
The method for underwater fish recognition system is
built based on extraction of DWT features in the first step.
These features are tested by the classifier where the
output is obtained as the second step. These two steps are
done for both the training and the testing input images.
The framework of our underwater fish recognition
system is as shown fig 1.
A.FEATURE EXTRACTION
The feature extraction is the most important step in all
machine learning systems. Likewise in our system the
DWT features are extracted in each level of
decomposition method. Before extracting the features,
first the input images undergoes the pre-processing step
where the colour conversion of RGB to Gray colour
conversion is done. By using these pre-processed images
only the DWT features are extracted. The DWT features
will be having discrete level of wavelet transform
features. This feature extraction is done for various levels
of decomposition process. The features extracted are
saved as trained database that are used later in
classification process.
B.CLASSIFICATION
The same step is done for both the training set and testing
sets. The extracted features are stored in the database
according to their equivalent index class for the
recognition. The features are extracted and are given as
the inputs for the classifier as they need two types of
inputs like trained database as one input and the tested
image features as another input. Then the SVM classifier

separate the image class according to the species in the
present.

III. RESULTS
The underwater fish recognition system based on DWT

Database. The database contains 7953 pictures of 1458
different species. The images are tested and classified by
using the SVM classifier. The size of images present in
the database are of 256X256 in size and is of 1458
different species. So as to calculate the performance of
our proposed system, the given database is separated into
two parts namely training and testing set of database
images. The DWT features are extracted and are tested
and classified by using the SVM classifier as explained
above.
