Abstract

Based on a resulting medial axis configuration of 2-D shapes, previously we proposed a new shape description called Chain of Circles (CoCs). This paper shows how the CoCs representation is robustly used in matching of shapes with various deformations. The shape dissimilarity between a pair of CoCs is first coarsely calculated via the matching process, then finely calculated between specific and salient parts of the shapes, and finally used for recognition. This hierarchical recognition scheme seems to be in accord with the human shape recognition and gives much computational efficiency.
