Abstract :
A novel automatic edge extraction algorithm, based on investigation of local histograms of small non-overlapping blocks of the output of the first derivative of a narrow 2D Gaussian filter, is presented. It is shown that the proposed algorithm provides the best trade-off between noise suppression and correct edge localisation
