【Abstract】 A fuzzy gradient method based on the character of gray gradient of the image edge is proposed. An image gray scale fuzzy matrix is constructed and a suitable membership function is selected. Genetic algorism is used to achieve the optimum parameters of the membership function. The edge points are determined and extracted according to the output of function. The edge detection is carried out. The experiment results show that this method has the ability to describe the edge crossing process and to improve the result of edge detection.更多还原
