Abstract
The ability to perceive moving object is an important visual modality. An optical flow, which represents a local velocity field caused by the moving objects, has been studied in the research field of computer vision[1]. The optical flow chip has been tried to be realized by J. Kramer et al[2]. We have tried to simplify the fundamental analog integrated circuit for motion detection combining biological systems with a simplified algorithm of the optical flow. In this paper, we show experimental results of a fabricated chip which contains unit circuits for the motion detection. Results of SPICE simulations, based on those results and the simplified algorithm, showed that the proposed circuit can detect the direction and speed of motion.
