I think training a head detector in all directions (front, two sides, back, up-down) together is not the solution, as current solutions usually use only one direction (front, back). I am try to train them separately, and later on, add their detecting result together... any other ideas @StevenPuttemans? Thanks!

@bruceyo, it is not very effective to open up topics that are more than 2 years old ... they talk about repository states that are lost and forgotton. So next time make your own question for that. You will need to train seperate models and then use the location of the detections to merge all the results. If you have enough models you can even use the different detections to do majority voting and ansuring that each head is detected in at least 2 models for example.

Check cascades from here: I remember that there was something for head and shoulders (upperbody?), but I'm not sure about the quality...

I have tried the "Head and shoulders" from this web site , it's different from those under the openCV codebase, but they are compatible. Even when setting the minimum size of detected "object" larger, it is slower than face detection (like 3x slower), but the detection is real good.
