A New Edge Detection Method based on Additions and Divisions

Edge is an important feature of an image and is required for image understanding. It provides important image information that can be used for image interpretation. Many techniques of edge detection have been developed. This paper proposes a new technique of edge detection that requires much lesser computation than Sobel’s method and performs better than Sobel’s method. The technique is based on additions and divisions. It makes use of a threshold value that is automatically computed by the program that implements this technique. The computation of the threshold value is very simple too.
