introduction: having a desirable image in a market can be considered as an asset for an organization. therefore, using proper approaches, managers of such organizations must monitor and manage the image of their organizations in order to achieve their organizational goals and their customer’s satisfaction. as an important sector of every society, managers of hospitals also must try their best t...

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...

Image fusion is a method for obtaining a highly informative image by merging the relative information of an object obtained from two or more image sources of the same scene. The satellite cameras give a single band panchromatic (PAN) image with high spatial information and multispectral (MS) image with more spectral information. The problem exists today is either PAN or MS image is available fr...

this research aims to assess the physicochemical properties, image features, textural and sensory qualities of dark chocolate made using coffee silver skin as a cocoa powder replacement which was substituted for 25%, 50%, 75% and 100% of the cocoa powder (by weight) in chocolates. the results indicated that there was significant differences between the chocolates prepared using 100% coffee skin...

Abstract: Stochastic models such as mixture models, graphical models, Markov random fields and hidden Markov models have key role in probabilistic data analysis. In this paper, we used Gaussian mixture model to the pixels of an image. The parameters of the model were estimated by EM-algorithm.   In addition pixel labeling corresponded to each pixel of true image was made by Bayes rule. In fact,...
