The code implements the optical flow algorithm described in Gautama, T. and Van Hulle, M.M. (2002). A Phase-based Approach to the Estimation of the Optical Flow Field Using Spatial Filtering,IEEE Trans. Neural Networks, 13(5), 1127--1136.

The algo proceeds in 3 steps
1. spatial filtering
2. phase gradient estimation
3. IOC using recurrent networks

Update of the algorithm itself: rather than using the goal programming network for solving the intersection-of-constraints, it now finds the solution analytically. Should have done this in the first place, but ah well ...
