Paper Abstract

A class of features, called "edge features," has been developed and applied to several problems of practical interest in image processing. These features are derived from a vector-valued function of the image called the "edge spectrum-" The edge spectrum at coordinate (x.,y) of the image describes the distribution of edge directions near (x,y). Several applications of edge features are discussed. One is considered in some detail. This application is to identify friendly aircraft descending for landing on an aircraft carrier. Identification is achieved by measuring wingspan - a good discriminant between the A6, A7, E2C and F.14. aircraft. For this purpose an edge feature was designed for locating the wing tips in the image. Wingspan was converted to physical dimension using range information and the known parameters of the optical system.
