Local and Regional Edge Detectors: Some Comparisons

Abstract

Consideration of the usefulness of edge information for use in segmentation or other intermediate-level picture operations has motivated a comparison of the accuracy and reliability of a number of directional edge operators. The Hueckel operator is singled out for comment, and an error in its derivation is noted. Another regional edge operator is introduced as being better suited to application on discrete pictures. Keywords: Image processing; Pattern recognition; Edge detection.
