Abstract

This demonstration shows how an inexpensive high frame-rate USB camera is used to emulate existing and proposed activity-driven event-based vision sensors. A PS3-Eye camera which runs at a maximum of 125 frames/second with colour QVGA (320×240) resolution is used to emulate several event-based vision sensors, including a Dynamic Vision Sensor (DVS), a colour-change sensitive DVS (cDVS), and a hybrid vision sensor with DVS+cDVS pixels. The emulator is integrated into the jAER software project for event-based real-time vision and is used to study use cases for future vision sensor designs.
