Abstract

Generalization of string languages describing shapes in order to apply them to analyze a contour of bones in hand radiographs is proposed in this paper. An algorithm to construct a fuzzy shape descriptor is introduced. Next, basing on the fuzzy descriptor, a univocal description by fuzzy interference is realized. In prospects this method will be used to erosion detection of hand bones visible in hand radiographs.
