Edge Detection of Digital Image Using Fuzzy Rule Based Technique

The edge detection in digital images based on fuzzy inference system has become popular todays. So, this paper proposes a simple and efficient method based on fuzzy inference rules without determining threshold value for edge detection in digital images .The approach of this algorithm to detect the edges of an input image by scanning it throughout using a 2*2 pixel window over the whole image pixel , It has 4 inputs corresponding to 4 pixels of scanning matrix and has one output identifying the pixel is review that if it is edge pixels .The Fuzzy system includes sixteen fuzzy rules to classify the pixels. The results of the implemented algorithm have been compared with the standard edge detection algorithm such as, Canny, Sobel, Prewitt and Roberts.
