Paper Abstract

Optical flow and its first order spatial derivatives can be computed by solving an overconstrained system of linear algebraic equations assuming that i) optical flow varies linearly over a small region of the image plane and ii) that the image brightness is stationary over time. Experimental results on sequences of synthetic and natural images show that the obtained optical flow is usually very similar to the true two-dimensional motion field.
