Melanocytic lesion images segmentation enforcing by spatial relations based declarative knowledge

Abstract

This paper presents a method for enforcing image segmentation. Method presented here is a part of a wider research - an image understanding system. Regions of the image, extracted by a basic segmentation process, belong to certain classes. Spatial relations are calculated for extracted regions of the image, according to the declared knowledge. Declarative knowledge in the form of semantic rules is used as a second step to eliminate errors in the basic segmentation process. The approach is generic, but in this case it is used for melanoma skin lesions diagnosis.
