Advanced Statistical Matrices for
Texture Characterization: Application
to Cell Classification
This paper presents new structural statistical matrices which are gray level size zone matrix
(SZM) texture descriptor variants. The SZM is based on the cooccurrences of size/intensity
of each flat zone (connected pixels with the same gray level). The first improvement
increases the information processed by merging multiple gray-level quantizations and
reduces the required parameter numbers. New improved descriptors were especially
designed for supervised cell texture classification. They are illustrated thanks to two
different databases built from quantitative cell biology. The second alternative characterizes
the DNA organization during the mitosis, according to zone intensities radial distribution.
The third variant is a matrix structure generalization for the fibrous texture analysis, by
changing the intensity/size pair into the length/orientation pair of each region.

Texture segmentation can be considered the most important problem, since human can distinguish different textures quit easily, but the automatic segmentation is quit complex and it is still an open problem for research. In this paper focus on implement novel supervised algorithm for multitexture segmentation and this algorithm based on blocking procedure where each image divide into block (16×16 pixels) and extract vector feature for each block to classification these block based on these feature. These feature extract using Box Counting Method (BCM). BCM generate single feature for each block and this feature not enough to characterize each block ,therefore, must be implement algorithm provide more than one slide for the image based on new method produce multithresolding, after this use BCM to generate single feature for each slide.

There are subsets of genes that have similar behavior under subsets of conditions, so we say that they coexpress, but behave independently under other subsets of conditions. Discovering such coexpressions can be helpful to uncover genomic knowledge such as gene networks or gene interactions. That is why, it is of utmost importance to make a simultaneous clustering of genes and conditions to identify clusters of genes that are coexpressed under clusters of conditions. This type of clustering is called biclustering. Biclustering is an NP-hard problem. Consequently, heuristic algorithms are typically used to approximate this problem by finding suboptimal solutions. In this paper, we make a new survey on clustering and biclustering of gene expression data, also called microarray data.

The analysis of proteins and messenger RNA is commonly used in the comparison of gene expression patterns in tissues or cells of different types and under distinct conditions. In gene expression analysis, normalization is a critical step as it guarantees the validity of downstream analyses. Data preprocessing is an indispensable step in the extraction and normalization of microarray gene expression data. The normalization of gene expression data is essential in ensuring accurate inferences. A number of normalization methods in high throughput sequencing studies are being employed. The preprocessing activity begins by a careful analysis of the gene expression data and usually involves the classification of many raw signal intensities into one expression value. The Robust Multiarray Average (RMA) is a normalization approach for microarrays that involves background correction, normalization and summarization of probe levels information without using MM probes (Lim et al., 2007). It is an algorithm commonly used in the creation of an expression matrix for Affymetrix data and is one of the most commonly used modes of preprocessing to normalize gene expression data. Values of raw intensity are initially background corrected and log2 transformed before being normalized. In order to generate an expression measure for probe sets on each array, a linear model is fitted to the normalized data.

Abstract The mammography is the most effective procedure to diagnosis the breast cancer at an early stage. This paper proposes mammogram image segmentation using Rough K-Means (RKM) clustering algorithm. The median filter is used for pre-processing of image and it is normally used to reduce noise in an image. The 14 Haralick features are extracted from mammogram image using Gray Level Co-occurrence Matrix (GLCM) for different angles. The features are clustered by K-Means, Fuzzy C-Means (FCM) and Rough K-Means algorithms to segment the region of interests for classification. The result of the segmentation algorithms compared and analyzed using Mean Square Error (MSE) and Root Means Square Error (RMSE). It is observed that the proposed method produces better results that the existing methods.

This research work proposes a new intelligent segmentation technique for functional Magnetic Resonance Imaging (fMRI). It has been implemented using an Echostate Neural Network (ESN). Segmentation is an important process that helps in identifying objects of the image. Existing segmentation methods are not able to exactly segment the complicated profile of the fMRI accurately. Segmentation of every pixel in the fMRI correctly helps in proper location of tumor. The presence of noise and artifacts poses a challenging problem in proper segmentation. The proposed ESN is an estimation method with energy minimization. The estimation property helps in better segmentation of the complicated profile of the fMRI. The performance of the new segmentation method is found to be better with higher peak signal to noise ratio (PSNR) of 61 when compared to the PSNR of the existing back-propagation algorithm (BPA) segmentation method which is 57.

Abstract-Microarrays are one of the latest breakthroughs in experimental molecular biology that allow monitoring of gene expression of tens of thousands of genes in parallel. Micro array analysis include many stages. Extracting samples from the cells, getting the gene expression matrix from the raw data, and data normalization which are low level analysis.Cluster analysis for genome-wide expression data from DNA micro array data is described as a high level analysis that uses standard statistical algorithms to arrange genes according to similarity patterns of expression levels. This paper presents a method for the number of clusters using the divisive hierarchical clustering, and k-means clustering of significant genes. The goal of this method is to identify genes that are strongly associated with disease in 12607 genes. Gene filtering is applied to identify the clusters. k-means shows that about four to seven genes or less than one percent of the genes account for the disease group which are the outliers, more than seventy percent falls as undefined group. The hierarchical clustering dendo gram shows clusters at two levels which shows again less than one percent of the genes are differentially expressed.

Light microscopy is the gold standard for investigating microscopic structures and pathological alterations in both human and animal models of disease. However, due to tedious manual interventions, quantification of histopathologic markers is classically performed on only a few 2D tissue sections, thus restricting measurements and observations to limited portions of the sample volume. Understanding vascular networks within tissues is a critical component to identifying pathophysiology. The work presented here introduces a methodology for multi-parametric quantification of vascular networks for whole-mount tissues. Our approach streamlines the histopathology workflow, enables observations within large 3D sample volumes, and provides opportunities for automated image analysis.

However, these algorithms tend to overestimate the dose distribution in tumors diagnosed in extracranial regions such as in the lung and head and neck regions where large inhomogeneities exist. Due to the inconsistencies seen in current calculation methods for extracranial treatments and the need for more precise radiation delivery, research has led to the creation and integration of improved calculation methods into treatment planning software.

Medical image segmentation is a frequent processing step in image understanding and computer aided diagnosis. In this paper, we propose medical image texture segmentation using texture filter. Three different image enhancement techniques are utilized to remove strong speckle noise as well enhance the weak boundaries of medical images. We propose to exploit the concept of range filtering to extract the texture content of medical image. Experiment is conducted on ImageCLEF2010 database. Results show the efficacy of our proposed medical image texture segmentation.

Color, texture, shape and luminance are the prominent features for image segmentation. Texture is an organized group of spatial repetitive arrangements in an image and it is a vital attribute in many image processing and computer vision applications. The objective of this work is to segment the texture sub images from the given arbitrary image. The main contribution of this work is to introduce “NEW” texture feature descriptor to the image segmentation field. The NEW texture descriptor labels the neighborhood pixels of a pixel in an image as N,W,NW,NE,WW,NN and NNE(N-North, W-West).To find the prediction value, the gradient of the intensity functions are calculated. Eight component binary vectors are formed and compared to prediction value. Finally end up with 256 possible vectors. Fuzzy c-means clustering is used to segment the similar regions in textural image Extensive experimentation shows that the proposed methodology works better for segmenting the texture images, and also segmentation performance are evaluated.
