Theoretical Considerations on a Family of Distance Transformations and Their Applications
The distance transformation (DT) was defined for processing binary pictures by Rosenfeld and Pfaltz (1967). It was also pointed out that the skeleton is an important concept in relation to the DT. The DT and the skeleton have been used for a variety of purposes, for example, description, data compression, thinning or smoothing of binary pictures. Levi and Montanari (1970) defined a grey weighted distance transformation (GWDT) and a grey weighted skeleton by introducing grey value information into the DT and skeleton of binary pictures. These transforms have been also used effectively for feature extraction, thinning or preprocessing of grey pictures.
