A Multi-scale Edge Detection Method Based on Modified Morphological Transform
基于改进形态学算子的多尺度边缘检测

The key to edge detection is to filter more noises while obtaining more edge details.A new multi-scale morphological method of edge detection based on contour structuring elements is proposed in this paper.This method realizes a modified morphological transform through regrouping the priorities of several morphological transforms based on contour structuring elements firstly.And then a new edge detector is defined by using the multi-scale operation of the modified morphological transform.Comparative study with other morphological methods reveals its superiority over de-noising capacity,edge detail protection and un-sensitivity to the shape of the structuring elements.
