Abstract :
In this paper, we study optical flow determination using a novel imaging device, correlation image sensor (CIS). The proposed method is based on the optical flow equation between intensity image and complex sinusoidally-modulated image captured simultaneously by CIS. Since it does not involve time derivative, only one frame is required for estimation. Moreover, the velocity limitation by the approximate frame differential is avoided
