A simple method for dominant point detection

Abstract

An efficient algorithm for dominant point detection is proposed in this paper. The concept of break points is used to determine an asymmetric region of support of each point on the curves. The curvature is then estimated by the cosine values to assess the degree of possibility of a point being a dominant point. Finally, the dominant points are located by finding the local curvature extreme among the determined asymmetric region of support. The proposed method needs no input parameter. The experimental results show that the new method is efficient and effective in detecting dominant points.
