Time to contact computation with a space-variant retina-like C-mos sensor

The first application of a new generation of space variant sampling visual sensor is described in this paper. Time to contact computation from optic flow is performed using a very simple system consisting of a space variant chip connected through a parallel port to a 486 based PC. Results of experiments will be reported.
