Multi-directions Gray-scale Morphology Edge Detection Algorithm
多方向灰度形态学边缘检测算法

This paper introduces a multi-directions algorithm for image edge detection based on mathematical morphology.In this algorithm,we analyse the multi-direction of edge in image and the multi-directions characteristic of structure elements,then we use these structure elements with morphology open-close filters in edge detection.This algorithm has succeeded in edge detection,and suppresses noise very well,it has better effect than other traditional edge detection methods of mathematical morphology.
