Abstract:
1. A method for indicating a similarity between two binary images A a i , A b j , said method being carried out by a processing unit of a system for analyzing similarities of images further including a storage device cooperating with said processing unit to store binary images, wherein the method comprises: a step for extracting a first set of primitives from a first binary image A a step for measuring the presence of a common piece of information within said binary images and delivering a similarity indicator ε* therefor, said indicator being calculated by the processing unit as the relative deviation between an overall maximum H and the average of two other local maximums H′ and H″, i.e.,  said maximums being determined from a distribution of the different orientations of pairs of primitives respectively resulting from two extracted sets of primitives.
