Fig. 2From: Unsupervised joint deconvolution and segmentation method for textured images: a Bayesian approach and an advanced sampling algorithmHierarchical model: the round/square nodes show the estimated/given variable. The xk are the textured images (Gaussian density) and the θk,γk are the texture parameters. ℓ is the label set (Potts field) and β is the label parameter (granularity coefficient). The observed image is y. See also the notation table (end of the paper)Back to article page
