Abstract

A new pyramid method for edge detection is presented. Optimal stack filters are designed for each pyramidal structure level generation. A template matching operator is used for the edge map finding at the top most pyramid level. The edge maps of all other pyramid levels including the bottom level are obtained through a procedure of interpolation, adjustment and smoothing based on their immediate higher levels. This method can resolve the problems of noise sensitivity, computational cost and multiresolution image analyses.
