Shape features in distance transforms
Carlo Arcelli, Luca Serino · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1993
Shape features characterizing patterns represented by their distance transform are illustrated. The role they can play in pattern decomposition is described with reference to a process based on the detection of a number of pixels significant for shape interpretation. Suitable sets of these pixels are regarded as feature sets, and used as seeds to be expanded into regions. After a merging phase, the regions originate a meaningful decomposition.
