Abstract

In the context of mobile robotics, we have evolved a Foveal Visual Pre-processor that detects and extract motion as well as shape. This F.V.P. makes a selective tracking of stimuli. The main interest of this model inspired by the vertebrate retina is its response to stationary or moving stimuli: they can be distinguished according to both their shapes and velocities. This model is adaptive and its multi-resolution characteristics allow the detection of a wide range of velocities. The developed model consists in three parts: the Retina module which is in charge of the visual processing, the process module which processes the neural signals and extracts the velocity vector and the spatial frequencies (i.e.: the shape of the stimulus) and the control module which directs the fovea onto the stimulus and tracks it. The results obtained from the analyses of scenes with, in a first step, a unique moving object have validated the chosen control. One of the interests of our model is the possibility of selecting one stimulus and tracking it. The developed system has a good precision and the object is always caught by the fovea. Indeed, as the biological retina, our sensor adapts to the various conditions of illumination and is robust to noise.
