Research Interests

Audio-Visual Interaction and Collaborative Environment
We have been creating technologies for audio-visual communication between humans, and between the human and the computer. A system has been developed to resolve the lip-synchronization problem in video conferencing. It has also been used in movie dubbing and cartoon animation. Research activities also involve using the video camera to track the face and lip movements of a user for lipreading, enhancing speech recognition in a noisy environment, and as a means of human-computer interfaces. Together with spatialized audio and lip-synchronized avatars, these techniques are integrated to create an immersive collaborative environment that will replace the existing videoconferencing platform.
Video Coding and Multimedia Communication
We have contributed to international standards such as ITU-T H.263, MPEG-4, and MPEG-7. Others lead to research projects that go beyond the existing standards. Active research topics include: standard-compliant encoder optimization, e.g., efficient motion estimation and rate control, streaming and watermarking of audio, video, and 3D objects, network-adaptive coding and transmission, error resilience, quality of service, and other networking issues, region/object-based video coding, and indexing and retrieval of multimedia databases.
