On edge detection
IEEE Transactions on Software Engineering
Edge detection is the process that attempts to characterize the intensity changes in the image in terms of the physical processes that have originated them. A critical, intermediate goal of edge detection is the detection and characterization of significant intensity changes. This paper discusses this part of the edge detection problem. To characterize the types of intensity changes derivatives of different types, and possibly different scales, are needed. Thus, we consider this part of edgepmid:21869334 fatcat:oo7pqazxmjd7zoght7m6lbz7je
