Abstract
Starting from a binary digital image, a multi-valued pyramid is built and s uitably treated, so that shape and topology properties of the pattern are p reserved satisfactorily at all resolution levels. The multi-valued pyramid can then be used as input data to any grey-level skeletonization algorithm. In this way, a multi-resolution skeleton is computed, which could be usefu l in many image analysis tasks. (C) 2001 Elsevier Science B.V. All rights r eserved.
