Methods and perspectives in face tracking based on human perception

This chapter aims at analyzing the role of human early vision in image and video processing, with particular reference to face perception, recognition, and tracking. To this aim, the change of perspective in approaching image processing-based problems where the decoder (human eye) plays a central role is analysed and discussed. In particular, the main topics of this contribution are some important neurological results that have been successfully used in face detection and recognition, as well as those that seem to be promising in giving new and powerful tools for face tracking, which remains a less investigated topic from this new standpoint.
