Answer 1

This code is using OpenCV's implementation of the HOG detector, see this tutorial for a good explanation of the algorithm. This classifier is trained on whole body images of people standing more or less upright, and that is what it will detect. If you want to detect people when you can see their face, but not the whole of their body, then take a look at OpenCV's face detection algorithms instead.
