Retinal Ganglion Cell Software and FPGA Implementation for Object Detection and Tracking


Moeys, Diederik Paul; Delbruck, Tobias; Rios-Navarro, Antonio; Linares-Barranco, Alejandro (2016). Retinal Ganglion Cell Software and FPGA Implementation for Object Detection and Tracking. In: IEEE International Symposium on Circuits and Systems (ISCAS) 2016, Montreal, Canada, 22 May 2016 - 25 May 2016, 1434-1437.

Abstract

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.
