Edge Detection through Fuzzy System using Type I Format

This paper proposes the implementation of a very simple but efficient fuzzy logic based algorithm to detect the edges of an image with desired level of threshold values. The approach begins by scanning the images using floating 2x2 pixel window. FIS is designed with 4 inputs, whose output is further used in proposed algorithm to reduce the noise in the edges produced by the FIS. This algorithm is compared with six standard algorithms and one more system is also proposed which gives the direct comparison of these six algorithms visually
