| Abstract: | This paper gives a method of image edge detection,using multiple edge features and fuzzy reasoning.To effectively extract edges,edge pixels are classified according to the difference of intensity distribution,and multiple effective edge features are defined.Edges are detected by applying fuzzy reasoning (min max centriod method),based on local image edge characteristics.Finally,the given algorithm is tested on several images.Comparison is made with standard edge detection techniques. |
