Abstract

In this paper we propose a novel technique for the corner detection of plane curves. This corner detector is given through the triangle-area representation method, whose underlying idea rests on the maximum property of the local area at the corner point. Therefore, the method can be realized easily and is of high accuracy under some appropriate scale (triangle-length scale). The experimental results of different types of corners are presented.
