| Abstract : | 1 Edges are useful features for structural image analysis, but the output of standard edge detectors must be thresholded to remove the many spurious edges. This paper describes experiments with both new and old techniques for: 1) automatically determining appropriate edge threshold values, and 2) determining edge saliency (as alternatives to gradient magnitude)., |
