SIMULATION AND IMPLEMENTATION OF EDGE DETECTION ALGORITHM 1

Abstract- In this paper, we present the software implementation of a modified version of canny edge detection algorithm, which result in significantly increased edge detection performance. The results of various gradient based filters: Roberts, Sobel and Prewitt are also observed. The edge tracking step in the canny edge detection algorithm is replaced by considering the horizontal and vertical components of the image, resulting in improved performance of the detection algorithm. The implementation of the detection algorithm is done by using MATLAB tool. The results show the effectiveness of the proposed approach
