Nowadays, the general topic of human face detection becomes a very important research field. This is due to the needs of good working face detection methods have reached a high level and the current systems do have a high optimisation potential. In this book, a hybrid real-time face detection system will be introduced that is able to deal with colour images in HD resolution. This system is able to detect multiple faces on a single input image and consists of three main components, motion detection, skin colour detection and applying an Adaboost algorithm.
