Face detection and eye tracking in real-time are the first steps for head gesture recognition and/or face expression recognition. We propose a new filter (Circle-Frequency Filter) to detect and track a face feature point (the point between the eyes). It is rotation invariant and fairly robust to a pretty wide range of face orientation. The calculation is simple. Therefore, combining a technique of skin-color region extraction, we can detect and track the face feature point in a video stream in real-time. We implement the system on a SGl O2 workstation. The video image size is 320x240 pixels. The system processes images at seven frames per second in the detection mode, and 13 frames per second in the tracking mode without any special hardware.
