ABSTRACT:
A method is disclosed for measuring similarity between images, comprising the performance of the following steps for each of the images: segmentation of the image into segments, classification of the segments as a function of their orientation to give classes, calculation of a histogram of the number of segments as a function of class, calculation of a histogram of the number of pixels belonging to the segments of one and the same class as a function of class, and comparing, for each image, the histograms calculated above to their respective histograms calculated for each of the rest of the images to give a measurement of similarity.
