The code contained in this archive comes from Professor John Barron's
collection of optical flow algorithms. The original code comes
from ftp://csd.uwo.ca/pub/vision/. The only modifications made to this
code is the additional of endianness coverters to allow Intel machines
to deal with the Sun Rasterfile headers.

anandan implements Anandan's multiresolution flow algorithm
horn implements Horn & Schunck's gradient and smoothness based algorithm
nagel implements Nagel's oriented smoothness algorithm
fleet implements Fleet and Jepson's frequency based algorithm
lucas implements the Lucas and Kanade matching algorithm

The psflow program takes the output files produced by these algorithms
and produces graphical representations of the vector flow fields.
