19.05.2009Dr. Pierre Elbischger - MIP1/ISAP'SS092Sharpening using the Laplacian (1)The principal of sharpening is to highlight fine details in an image or enhance details that have been blurred, either in error or as a natural effect of a particular method of image acquisition. The Nabla operation can be replaced by the convolution of the image with the Laplacian of Gaussian filter kernel.Sharpening, using the Laplacian
