Abstract

Abstract In this paper segmentation is considered to be performed as a step-by-step refinement of results. In a preliminary step a line-oriented method produces results which are hints (hypotheses) at specific objects. The strength and the type of a hint determines application of a region-oriented procedure or a line-oriented procedure under modified conditions. The results obtained are regions described by their contours, linearly shaped objects described by their skeletons, and very small regions (spots) described by pairs of coordinates. Results are scored with confidence values and may be verified by application of alternative segmentation procedures. In the following the methods of segmentation and their integration are discussed and results are presented.
