ABSTRACT :

The Canny edge detector is widely used in computer vision to locate sharp intensity changes and to find object boundaries in an image. The construction of a pre-processing filtering tool for edge detection and segmentation tasks is still a challenging matter. In this paper the revision of the Canny edge detector is done to improve its detection accuracy. This paper proposes an edge sharpening filter to sharpen the edges of an image prior to detection and then apply the canny detector for the better results. The difference in the output can be observed by comparing the results of edge detection under normal and filtered conditions. This work is implemented using MATLAB 7.10.0.
