摘要:
A new method, based on k-cosine, is proposed for the determination of region of support and detection of significant points of digitized curves. A new measure of significance, based on k-cosine, is introduced. The procedure is parallel and requires no input parameter. A polygonal approximation is suggested by joining the successive significant points.
