I work on Neuromorphic Event based Vision, my lab develops several event based cameras and associated computer vision and machine learning algorithms with the goal to build complete neuromorphic systems (sensors, brain-like computation devices, brain and retina prosthetics , and algorithms). My interest is to solve open problems both in robot navigation, object recognition, medecine, life long learning, robotics and general AI. I develop event based SLAM, tracking, object recognition, using neuromoprhic time based techniques that I pioneered a decade ago.

The neuromorphic ATIS event-based vision sensor (left) takes in a traffic intersection (right)[top]. The sensor outputs a measurement only when the light striking a pixel shifts by a preset amount. When the light level crosses that threshold, circuitry attached to the pixel produces a change-detection event and triggers an illuminance measurement, encoded by the interval between two more events. The results for the entire pixel array can be viewed for a given time slice, but only changing pixels contribute to these images: the positive and negative level-crossing events [white and black, respectively, middle right] and associated illuminance measurements [nonblack areas, bottom right]
