Abstract

An edge detection or enhancement method for image processing in which, for each image pixel P, there is calculated a value E(P) where:- E(P)=¦A-E¦+¦B-F¦+¦C-G¦+¦H-D¦ A high value of E(P) indicates that the pixel P lies on an edge. For image enhancement the valve E(P) may be added to P. <IMAGE>
