Abstract

The detection of dominant points is an important problem in shape recognition. In this paper, the dominant point is divided into two kinds of point: corner point and tangent point, and a two stage method to detect the dominant point is proposed. The corner points are first detected based on the curvature smoothed by Gaussian filter, and tangent points are detected based on the curvature accumulation curve with the commonly used splitting method.
