This program is the haar opencv face detector slightly modified for ease of use
There are command line options available to avoid the need to use the gui (see
facedetect.cpp for the command line option format

This program needs fltk installed.  It can be downloaded online.

The standard facedetect.cpp works at one scale.  Our facedetect pyarmids the
image up and down to allow processing at more scales.  This can also be
achieved via the cvHaarDetectObjects function.   

This program has only been tested with uncompressed avi files
