We introduce a multi-spectral MRI segmentation technique based on approximate reducts derived from the data mining paradigm of the theory of rough sets. We use genetic algorithms to tune the parameterized attributes and search for the best segmentation models based on approximate reducts.

We discuss a special kind of rough inclusions and its relation to fuzzy inclusions. One of four conditions of rough inclusions is detailed and a rough inclusion which satisfies the detailed condition as well as an additional condition is called a 'meticulous rough inclusion'. We show that a meticulous rough inclusion is closed with respect to upper and lower closure operators defined for a rough inclusion. We discuss conditions for a rough inclusion to be a meticulous rough inclusion. Moreover, the relations between meticulous rough inclusions and fuzzy inclusions are investigated. Sufficient conditions for a fuzzy inclusion defined by an implication function to be a meticulous rough inclusion are given. Examples of fuzzy inclusions which are meticulous rough inclusions are presented.
