Irregular Tree-Structured Bayesian Networks

ITSBN for unsupervised image segmentation can be summarized as the figure above. This work is submitted to MLSP 2011 [pdf]. The latest version of ITSBN MATLAB code is made available here [.zip]. (version 2.3.0, released May 31, 2011). Some results (from version 2.1.4) are shown in the figure on the left panel. More updated (of course, better) results are shown here.
