General-purpose segmentation system using knowledge on images and segmentation operators

In this paper we describe a general-purpose segmentation module, defined as a set of basic operators with parameters. This module uses explicit knowledge about these operators, in order to select the ones that are best suited to the present treatment and to determine their parameters and thresholds dynamically, according to the class of the image to be segmented. Three examples of the segmentation process involved in different applications are given.
