Supervised MLE-Based Parameter Learning,ameter learning. The learning scheme was proposed first for homogeneous textures in (Gimel’farb, 1996a) and then generalized to piecewise‐homogeneous ones in (Gimel’farb, 1996b, 1996c). It recovers both the interaction structure and potentials from a given training sample (grayscale image or/and reg

This chapter presents results of simulation of various natural image textures taken from the MIT Media Laboratory “VisTex” image database (Pickard et al., 1995) or obtained by digitizing some examples from the album of Brodatz (1966). First, we consider the self-similarity between the diffe

Experiments in Retrieving Natural Textures,measure is deduced from the Gibbs models of Eqs. (2.3) and (2.10) and is based on the model parameters that are learnt as described in Chapters 3 and 4. Most of these results were initially presented in (Jain and Gimel’farb, 1995; Gimel’farb and Jain, 1996).

Experiments in Segmenting Natural Textures,ditional Gibbs model of region maps in Eq. (2.26) suggests that to segment a piecewise-homogeneous grayscale texture we have to simply simulate the region maps relating to this texture. Such a segmentation is also based on the CSA that adapts the model potentials as to approximate the GL/RLH and GLC
