Implement BBF / ICF for object (face) detection.

edit

Are there any plans to introduce some additional object recognition functions? I'm working with head / face detection and I believe that these would be very good for my purposes and for OpenCV in general.

BBF = Brightness Binary Feature -- http://libccv.org/doc/doc-bbf/

ICF = Integral Channel Features -- http://www.loni.ucla.edu/~ztu/publication/dollarBMVC09ChnFtrs_0.pdf -- http://www.idiap.ch/~odobez/HAVSS/2012-10-HAVSS-Monday-Carincotte-HumanDetection-Tutorial.pdf -- Fastest pedestrian detector in the west is based on this I believe.

I think both would need training, but I think this would be a good next step in face detection and probably close to what commercial solutions use.
