WebEdge Detection. Finding edges is a fundamental problem in image processing, as edges define object boundaries and represent important structural properties in an image. There are many ways to perform edge detection. The Sobel method, or Sobel filter, is a gradient-based method that looks for strong changes in the first derivative of an image. http://www.owlnet.rice.edu/~elec539/Projects97/morphjrks/moredge.html
