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 am looking for)

+2  A: 

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..

Thanks, at a glimpse it seems promising, i'll dive into it and update.

It is an implementation of the general Viola and Jones cascade framework, but unfortunately it seems that the actual features used are not Haar features.

well it shouldnt be very complicated to try and implement that part yourself. Maybe this question http://stackoverflow.com/questions/1707620/viola-jones-face-detection-claims-180k-features could help you in generating the haar features
Amro
you are right it should not be too difficult. I was hoping someone already implemented it nonetheless
