Abstract: Edge Detection is a part of various image processing operations. Usually image is smoothen, sharpen even deblurred before performing edge detection so as to generate finer edges. This approach does works well in various cases, but there are cases where such things can damage the actual data present in image, which can be due to improper smoothening or de-blurring or excessive of both. In such cases edge detection might miss some inferior and less prominent edges which can be important part of image structure.
