This paper describes the software and FPGA
implementation of a Retinal Ganglion Cell model which detects
moving objects. It is shown how this processing, in conjunction
with a Dynamic Vision Sensor as its input, can be used to
extrapolate information about object position. Software-wise, a
system based on an array of these of RGCs has been developed in
order to obtain up to two trackers. These can track objects in a
scene, from a still observer, and get inhibited when saccadic
camera motion happens. The entire processing takes on average
1000 ns/event. A simplified version of this mechanism, with a mean
latency of 330 ns/event, at 50 MHz, has also been implemented in
a Spartan6 FPGA.European Commission FP7-ICT-600954Ministerio de Economía y Competitividad TEC2012-37868-C04-02Junta de Andalucía P12-TIC-130
