A Study on the Fast Method for Polygonal Approximation of Chain-Coded Plane Curves
이차원 곡선의 고속 다각형 근사화 방법에 관한 연구
Abstract
For shape description, a fast sequential method for polygonal approximation of chaincoded plane curves which are object boundaries is proposed. The proposed method performs polygonal approximation by use of the distance error from one point to a line, and its performance is enhanced by the smoothed slopes of lines. Furthermore, accumulated distance error and variable distance error threshold are proposed in order to consider and implement the visual characteristics of the human being.
