I don't know too much about face detection, can you anyone tell which algorithm the author is using? It doesn't work on a lot of pictures so I was wondering if this is the best face detection algorithm available?

I didn't look at the source in detail, but almost all face detection systems today (including those implemented in hardware in cameras) use a variant of Viola and Jones' Haar-Like Cascade Detector [1]. The major exception is work from CMU and PittPatt [2], which uses Neural Networks [3].

  I doubt that PittPatt uses NN. Here is the reference I found: Feature-Centric Evaluation for Efficient Cascaded Object Detection, Henry Schneiderman Maybe Schneiderman himself can clarify this :)

    Ah good point. I forgot that he had his own method, separate from Takeo's.

Hi, I put an introduction to the particular implementation behind it: https://github.com/liuliu/ccv/blob/current/doc/bbf.md https://github.com/liuliu/ccv/blob/current/doc/bbf.md You can checkout the first paper, it is a light reading.
