Abstract

In this paper the basic theory of a new edge detection algorithm is discussed, its application in image processing is analyzed and introduced as well. Considering the advantages of Grey system theory exploited in image edge detection, a mufti-scale morphological edge detection algorithm is proposed in this paper. At the end a new anti-noise edge detector is presented by improving the edge detector mentioned above in order to debut the detected edge efficiently and eliminate the influence of noise appropriately.
