چکیده

A new approach to multi−resolution modeling of images is introduced and applied to the task of semi−unsupervised texture segmentation using Gaussian Markov random fields (GMRFs). It is shown that traditional GMRF modeling of multi−resolution coefficients is incapable of accounting for the non−Gaussian statistics which often characterize the multi−resolution coefficients. On the other hand, the marginal distributions of the new approach can be closely modeled using a Gaussian distribution, and therefore lend itself efficiently to GMRF statistical modeling of images. Experimental results of texture segmentation using textures with non−Gaussian marginal distributions, suggest that the new framework is superior to traditional GMRF modeling of the multi−resolution coefficients for segmentation of non Gaussian textures.

­­Image Segmentation using Gaussian Mixture Model

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,...

Unsupervised texture segmentation using a statistical wavelet-based hierarchical multidata model

In this paper, we describe a new hidden Markov random field model, which we call hierarchical multi-data model, and which is based on a triplet of random fields (two hidden random fields and one observed field) in order to capture inter-scale and within-scale dependencies between various scales of resolution of wavelet-based texture features. We present a variation of the Iterated Conditional M...
