What is Optical Flow?
Optical flow, or optic flow, is the apparent motion of objects as perceived by an observer. As it can be understood, this motion can be due to actual movement of the observed objects, ...

Abstract
We describe a novel method for propagating disparity values using directional masks and a voting scheme. The driving force of the propagation direction is image gradient, making the process ...
