Abstract :
The morphological gradient operators of edge detection with multistructuring elements are given for gray-scale image. According to geometry feature of image, the multistructuring 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.
