Abstract :
In the previous research, we proposed an oculomotor system which expanded the limits of velocity measurement using spatiotemporal differentiation method. It was proved that the accurate optical flow was estimated at large object velocity by using this system. In this paper, we propose optical flow estimation method using oculomotor system where multiple objects on image move independently at large velocity. We suggest applying oculomotor system separately to regions of the same object motion. Using this approach, high accuracy of optical flow estimation can be obtained in case of multiple objects on image moving independently at a large velocity.
