Research on Edge Detection of Gray-scale Image Corrupted by Noise Based on Multi-structuring Elements

摘要

The morphological gradient operators of edge detection with multi-structuring elements are given for gray-scale image. According to geometry feature of image,the multi-structuring elements are selected to image details matching. Not only is the fine edge gathered, but also the noise restrained fiercely. It is showed by the experiments that the method is better than the classical edge detection.
