【Abstract】 A multi-scale edge detection method based on the mathe matical morpho-logy is proposed. Multiscale primitives are defined to be in agr ee ment with the spatial size of image objects to implement the multi-scale analy sis. This paper analyses features of edge detection on different sizes. Making u se o f advantages of morphological method to describe grayscale image, gray-scale pr ism structuring element and an extensive morphological operator are defi ned. Structural elements of different sizes are used to extract features at diff erent scales,and the edge points are extracted by using non-maximal operation technique, and it is compared with other morphology edge detectors. Experimental res ults obtained by applying the edge detectors on a real image with and without no ise are presented.更多还原
