Abstract :
We demonstrate an asynchronous address event representation (AER) motion detection sensor [1][2], that only responds to motions with speed higher than a tunable threshold. Each pixel in the sensor can individually monitor the relative change in light intensity and report a digital event if a threshold is reached. The output of the sensor is not a frame, but a stream of asynchronous digital events. By adjusting a variable slow-motion filter, low speed motion can be filtered.
