1. A method for detecting biologically relevant structures in a hierarchical fashion comprising: a) performing gland segmentation on the luminance channel to produce gland boundaries; b) calculating morphological features for each gland; c) classifying and labeling the morphological features for each gland as either malignant or benign; d) performing MRF iteration using the labeling in step (c) as a the starting point to produce a final labeling; and e) consolidating glands labeled as malignant into regions.
