    We propose and evaluate a mechanism for resolving the segmentation of overlapping chromosomes using trainable models of the expected banding appearance. The models consist of templates of sub-chromosome length band profiles. Candidate chromosome segments are classified according to their responses to the entire set of templates, and matched on the basis of the classifications. Evaluation of the models using a set of annotated banding profiles yields correct classification rates of 90.8% for isolated chromosomes, and 55.4% for chromosome fragments; 70.6% of overlapping chromosome pairs, simulated using the profile data set, are correctly resolved. © 1999 Pattern Recognition Society.
