SAVI: an actively controlled teleconferencing system

摘要

A Stereo Active Vision Interface (SAVI) is introduced which detects frontal faces in real world environments and performs particular active control tasks dependent on hand gestures given by the person the system attends to. The SAVI system is thought of as a smart user interface for teleconferencing, telemedicine, and distance learning applications. To reduce the search space in the visual scene the processing is started with the detection of connected skin colour regions applying a new Radial scanline algorithm. Subsequently, in the most salient skin colour region facial features are searched for while the skin colour blob is Actively kept in the centre of the visual field of the camera system.
