Abstract

Based on an image model of smooth regions separated by scaled discontinuities we compare two multi-scale approaches to the problem of edge detection and characterization in two-dimensional images from X-ray (CT) and magnetic resonance tomography (MR). Both approaches have been evaluated and compared on both synthetic images reassembling characteristic properties of tomograms and real MR images from the human brain.
