Abstract:

A new algorithm is proposed for detection of corners and other high curvature points in planar curves. A corner is defined as a location where a triangle with specified opening angle and size can be inscribed in the curve. The tests compare the new algorithm to four alternative algorithms for corner detection. The algorithms discussed are available for online testing over the Internet.
