The selection of edge detectors using local image structure

This paper summarizes a system, called SED, “Selection-of Edge Detectors”, which is able to automatically select edge detectors and their scales to extract a given edge. The basic organization of the SED system is a collection of edge detectors within a knowledge structure about the characteristics of the given edge, the properties of the detectors and the mutual relation between them. The combination of this information in the selection process provides a basis for avoiding a combinatorial search for appropriate edge detectors. We illustrate our approach by an example
