Abstract: Quick recognizing and matching of planar irregular curve is mainly used in image identify and object’s matching. This paper presents a new approach which chooses by key features quickly and then matches details after researching and comparing research products. The result of this method is content to planar irregular curve recognizing and matching by abstracting key features of a series of discrete points which makes up the planar irregular curve to choose quickly, and then comparing detail features, analyzing fluctuation tendency. It is proved that the gived method is stable, efficient and applicable.

Key words: planar irregular curve, recognizing and matching, discrete point set, turning points, curvature
