The impulse RETINA: A smart velocity sensor

The model Retina developed by the laboratory LACOS (University of le Havre, France) in collaboration with the A.B. Kogan research institute for neurocybernetics (Rostov-state University, Russia) is a retinal neural network permitting a pre-processing of foveal vision. This model is adaptative and its multi-resolution allows it to detect a large scale of velocities. We use the Retina to detect the motion and extract the velocity vector of a time sequence image. From impulse output signals of Retina we extract the pertinent parameters which encode the motion by time frequency analysis. The final aim is to implement this sensor on a mobile robot.
