This work extents the Hidden Markov Chain (HMC) model for the unsupervised segmentation of multicomponent images. Although the vectorial extension of the model is almost straightforward, we are faced to the problem of estimating a mixture of non-Gaussian multidimensional densities. In this work, we adopt an Independent Component Analysis (ICA) approach that allows the mutual dependance between the layers to be taken into account in the segmentation process. Classification results on a four… CONTINUE READING
