Vision-Based Facial Analysis for Human-Computer Intelligent Interface

The human face is a powerful mean of communication. We use it constantly, naturally and effortlessly not only to identify one from another, but also to transmit information about our feelings. Such natural style of communication with machines is the ultimate goal in Human-Computer Intelligent Interface.

The overall goal and motivation of this research line is to provide the computers with the vision-based ability to detect, identify, and understand faces and facial expressions so that a very natural communication channel between humans and computers can be established. Computer vision algorithms for facial analysis also find application in surveillance systems, video games and entertainment, virtual agents, video conferencing, etc.

The figure above illustrates the overview of the vision-based facial analysis system we have developed. Most parts of this system have been implemented in real-time and integrated to a multimedia, multi-modal, web-based Computer Travel Companion.

More specifically, our research on facial analysis includes algorithms for:

1. Information-Based Maximum Discrimination Learning.

2. Face Detection in Complex Background. ( Online Demo )

3. Facial Feature Detection.

4. Real-Time Tracking of Faces and Facial Features of Multiple People. (MPEG videos)

5. Gesture Analysis Based on Head Position.

6. Feature-Based Head Pose Tracking.

7. Embeded Face and Facial Expression Recognition. (MPEG videos)
