AUTOMATIC FACE DETECTION AND FEATURES TRACING

The system is intended for automatic real-time face detection and tracing of its typical features (eyes, mouth, eyebrows, nose). Web-camera is used as an input devise, which provides image sequence in RGB format (24 bit) with 10 frames per second rate. Input image size is 320*240 pixels. Detected face completely locates in camera view and not interfered by other objects. Face displacement is in range of 10. Illumination conditions are typical for office. The results of eyebrows, nose and mouth detection are approximated by splines with use of several feature points. The results of eyes detection are defined as: flag "eye is opened/closed", center and radius of appropriate circle.

Figure above shows the examples of face detection. Detected features are represented as graphical elements for further real-time visualization of virtual characters by computer graphics methods.
