Only "example.m" and "optical_flow.m" have been properly documented.
The code is an implementation of the phase-based 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.
I have modified the algorithm by leaving out the Goal Programming
Network and have replaced it by an analytical solution to the
intersection-of-constraints (the original algorithm is still available
as optical_flow_orig.m)
The code has been tested on Solaris (Matlab 5.3 R11) and Linux (Matlab
6.0 R12), and it works fine.
To check the performance, run the example.m script:
Coverage: 32.02 %
Angular error (full): 4.1771 deg (3.2145 deg)
If the errors deviate from these values, there is probably something
wrong. Feel free to hack in or, alternatively, to email me.

example.m example script
optical_flow.m optical flow algorithm
eval_flow.m evaluate obtained OF (only if desired OF is available)
vis_flow.m visualise OF
read_sequence.m read image sequence
read_flow.m read OF (Barron's format)
rastread.m read Sun raster file
yosemite/ contains yosemite sequence + desired flow
% OBSOLETE:
optical_flow_orig.m original optical flow algorithm
gpn_ada.m Goal Programming Network (calls the mex function)
gpn_ada_mex.c source
gpn_ada_mex.mexglx precompiled for linux
gpn_ada_mex.mexsol precompiled for Solaris
gpn_ada_mex.dll precompiled for windows
