Abstract :
Motion Computation, also called Optical Flow, consists of measuring the motion of an entity attending to the modulus (how fast) and the phase (direction) of its movement. There are a plethora of different models and algorithms whereas none of them cover all problems associated to the real world. Our contribution presents a novel customizable architecture, including resource usage and performance, of a neuromorphic robust optical flow adjustable platform, although its main drawback is the elevated computational complexity. Bioinspiration and robustness properties of the final system provides an extended set of applications fields.
