This video presents a detailed description of the brightness constancy constraint imposed in the optical flow for the motion estimation. It also discusses the aperture problem in optical flow, and the need for imposing the smoothness constraints. Smoothness constraints proposed by Horn and Schunk are also presented in detail.
