Abstract: Edge detection is one of the most important techniques in image processing. In spite of 20 years of research, the need for general edge detector is still felt. The key uncertainty in the edge detection algorithm is Threshold decision. To deal with uncertainty of information, soft computing approach is a good mathematical framework. In this work, we used fuzzy logic for Automatic Thresholding and generated threshold is used with different methods for edge detection. The results obtained from the proposed method are found to be comparable to those from many well known edge detector. However, the values of the input parameters providing the appreciable results in the proposed detector.
