High performance in real-time is one of today's challenge of embedded Computer Vision. The study of the human vision models inspires several solutions. The bio-inspired method used by the BVS-Tech component caught the attention of the community with its hardware characteristics and its application in different industrial projects. However, the lack of mathematical formalization and simulation of the method does not allow to analyse it on academical databases.This thesis focused on the understanding, the formalization and the reproduction of the method. The mathematical model and the simulator produced allowed to validate the concept on artificial images, to analyse its behaviour and performances in a specific application. The promising results shows, however, the strong influence of several parameters. Two extensions of the method have recently been proposed: the automatic adaptation of the feature inputs and the prediction integration.
