Abstract: A recognition method for recognition between a first and second object represented by at least one first image and at least one second image, includes: defining a plurality of rectangular assemblies of random pixels; filtering the first image with first n filters obtained from the assemblies of pixels to obtain n first filtered matrices; classifying the n first filtered matrices by providing a first centre and a first radius within a space of N dimensions; filtering the second image with the first n filters to obtain n second filtered matrices; classifying the n second filtered matrices by providing a second centre within the space of N dimensions; comparing the first centre and first radius with the second centre; whereby recognition between the object and second object has if at least one second centre lies at a distance from the first centre which is less than or equal to at least one first radius.
