texture image analysis is one of the most important working realms of image processing in medical sciences and industry. up to present, different approaches have been proposed for segmentation of texture images. in this paper, we offered unsupervised texture image segmentation based on markov random field (mrf) model. first, we used gabor filter with different parameters’ (frequency, orientatio...

The execution of scientific applications needs high-processing computers and requires massive storage. This resulted in deploying a distributed environment with high performance extensive Applications processed cloud platforms face intolerable delays due to data movement across the centres. Optimized distribution datasets among global centres has become an essential issue environment. work prop...

We introduce the independent factor analysis (IFA) method for recovering independent hidden sources from their observed mixtures. IFA generalizes and uniies ordinary factor analysis (FA), principal component analysis (PCA), and independent component analysis (ICA), and can handle not only square noiseless mixing, but also the general case where the number of mixtures diiers from the number of s...

We develop a novel method for source separation and apply it to natural images. It is a specialization of independent factor analysis (IFA) but overcomes generic IFA problems and finds many independent sources in few observations. A fast and robust EM learning algorithm produces an over-complete basis. Compared to standard approaches our method generates superior codes in terms of population sp...

Multilook processing is commonly used in SAR image formation in order to reduce the speckle noise. We propose two new mutlilook techniques for improving the radiometric resolution without altering the geometric resolution and characteristics of the impulse response. These techniques are based on the formation of looks with different bandwidths. The final image is formed by giving each look a pr...

The QUANTA Flash(®) CTD Screen Plus is a chemiluminescent immunoassay (CIA) for the detection of the major antinuclear antibodies (ANA) on the BIO-FLASH(®) platform. NOVA View(®) is an automated fluorescence microscope that acquires digital images of indirect immunofluorescent assay (IFA) slides. Our goal was to evaluate the clinical performance of the two automated systems and compare their pe...

template matching is a widely used technique in many of image processing and machine vision applications. in this paper we propose a new as well as a fast and reliable template matching algorithm which is invariant to rotation, scale, translation and brightness (rstb) changes. for this purpose, we adopt the idea of ring projection transform (rpt) of image. in the proposed algorithm, two novel s...

B. anthracis is the causative agent of anthrax. Pathogenesis is primarily mediated through the exotoxins lethal factor and edema factor, which bind protective antigen (PA) to gain entry into the host cell. The current anthrax vaccine (AVA, Biothrax) consists of aluminum-adsorbed cell-free filtrates of unencapsulated B. anthracis, wherein PA is thought to be the principle target of neutralizatio...
