A signed spatial contrast event spike retina chip
(IEEE Computer Society, 2010)
Reported AER (Address Event Representation) contrast retinae perform a contrast computation based on the ratio between a pixel's local light intensity and a spatially weighted average of its neighbourhood. This results in ...
