I was using "Liu Liu's algorithm" in a colloquial way. Should have been more specific and used, "the algorithm which Liu Liu implemented". As far as robustness is concerned I guess a lot depends on the quality of the training. The haar-caascade used in openCV is very well trained and generates few false +/-'ves. I wanted to know how this particular implementation of DPM performed.
