Description
Summary:An overview of the various methods and algorithms for edge detection in digital images is given in this survey paper. A fundamental issue in image processing is edge detection, which involves in locating the borders which separates various regions in an image. The survey starts with an explanation of edges and their importance in an image analysis, then reviews some of the most widely used edge detection techniques, including the canny edge detector, the Sobel operator, and the Laplacian of gaussian. The following section discusses some of the drawbacks and shortcomings of these techniques. A discussion of current trends and potential future directions in the field of edge detection rounds out the survey.
