Matlab implementation of Haar feature extraction

Does anyone know of a (purely) matlab implementation of Haar feature extraction (the kind used in Viola&Jones object detection algorithm)? (I ran across a matlab binding to Opencv's implementation but this is not what I a开发者_C百科m looking for)

I came across this code published as part of a Google Summer of Code 2007 project under GNU GPLv2 license.

Face detection for F-spot

Note that I haven't tested it myself, just thought it could be useful for you..
