Abstract: In this demo we propose a method for computing real time convolution on AER images. For that we use signed events. The AER events produced on an AER retina or an image/video to AER conversor, are processed using a probabilistic multi event mapper that produces more than one event for each incoming event according to an assigned probability. Kernel convolution size are limited by mapping tables size (on board RAM) and AER bus bandwidth. On reconstruction signed events needs to be simplified (subtracted) to get final convolved image. For that two different methods are proposed.
