— The normalized configuration entropy, based on the theory of information, when applied to the image of heterogeneous media, points out a characteristic length of the disorder, `opt, at which we calculate the optical properties. The models we propose make a partition of the image between percolated and non percolated cells of size `opt, in which we calculate effective dielectric functions. Two...
While a variety of software packages are available for analyzing two-dimensional electrophoresis (2-DE) gel images, no comparisons between these packages have been published, making it difficult for end users to determine which package would best meet their needs. The goal here was to develop a set of tests to quantitatively evaluate and then compare two software packages, Melanie 3.0 and Z3, i...
conclusion tout lecteur de théâtre se doit d’être un metteur en scène en puissance. le texte dramatique est en effet ouvert aux possibles de l’imaginaire ; en l’absence de scène, le lecteur s’invente un parti pris, visualise les personnages en action et donne à l’espace les couleurs, les dimensions et les formes qui correspondent aux caprices de son imagination. or dans ruyblas, hugo démultipl...
Biometrics is automated tool of recognizing a person depends on physiological or behavioral characteristics. A palm vein is a new member of pattern recognition and biometrics family, has attracted much of the research attention. This paper discusses about the image enhancement operation such as histogram equalization, de-correlation stretch, and contrast stretch etc. which results a quite enhan...
CT image De-noising is an important research topic both in image processing and biomedical engineering. Independent component analysis (ICA) is a statistical technique where the goal is to represent a set of random variables as a linear transformation of statistically independent component variables. The curvelet transform as a multiscale transform has directional parameters occurs at all scale...
2 Dimensional Electrophoresis Gel Registration Using Point Matching and Local Image-Based Refinement
Recently, proteomics research has become a large growth area in the biosciences. Studies involve differential analysis of large sets of 2-D Electrophoresis (2-DE) gels. We present a robust and accurate 2-DE gel alignment algorithm which combines point matching and local image-based refinement. The algorithm uses a novel combination of Euclidian, shape context, image and feature based attributes...
The studies to gather, systematize, scrutinize, and deduce numerical information from data is known as statistics. Min, max, mean, mode, midpoint, median, variance, standard deviation, covariance, histogram etc are the important image statistics used in various root level field of image processing and computer vision like Image enhancement [1-3], image restoration [2,3], image de-blurring [2], ...
Solar cell is known as a sustainable and environment friendly source of energy in nature. It converts sunlight directly into electricity with zero emission and also without side-effects on the environment. But, solar cells have optical and mechanical defects which include the type of micro crack, the size of crack, and the noise from electrical or electromechanical interference during the image...
Thin-section petrography is a crucial tool for the study of archaeological ceramics, and in recent years, image analysis has emerged as a powerful quantitative enhancement of that tool. Exploratory applications of image analysis to archaeological ceramic thin sections, and related work by sedimentary geologists, have indicated its usefulness to the field. In this paper, we first present the res...
Lorsqu’on s’interroge sur sa propre identité de l'Etat face au problème du sida, il faut certes y réfléchir un moment, tant les références personnelles en la matière peuvent être diverses. Nous avons toutes et tous une idée, une image, une réaction face au mot sida, ce que cela représente pour nous, nos proc...
