T-Rex Vision: Event-based vision sensor

Conventional cameras sense the world one image at the time, when all the pixels are activated within a short duration in order to capture the entire frame. By contrast, the emerging event sensor works entirely differently, and in a manner inspired by the human eye. The event sensor acts more like a change detector or a motion detector, like the T-Rex in Jurassic park! Instead of taking full images at a time, each pixel in the event sensor independently detects changes in the light intensity and generates a pixel-level event only when this change exceeds a certain threshold. This results in a continuous stream of events that can be used to sense the outside world at rates far faster than most conventional sensors are capable of, at a fraction of the power cost, and while transmitting far less data for downstream computation and storage.
