Introduction
Image understanding is a process representing the complex interaction between a computer
vision system and one or more digital images. According to (Tsotos, 1987), given a goal
or a reason for looking at a particular scene, image understanding system should produce
descriptions of both the images and the world scenes that the images represent. In terms
of medical imaging, image undertanding should lead to a successful interpretation of the
images and ideally contribute to an accurate diagnosis. Recent research aimed at machine
learning methods to develop strategies with the use of ad-hoc knowledge about the analysed
images and their context. Among them, one of the most promising approaches to explain
human image understanding is rule-based symbolic processing. Here, rules are extracted
through learning from examples or directly from expert knowledge. Many image under-
standing applications involve tasks such as image segmentation and edge detection that
extract significant information from an image which then often represents the input to a
