We work on image, video, audio, and multimedia communication systems.
We study research problems from a system viewpoint and emphasize on the use of both theoretical and practical approaches. Thus, in addition to the mathematical and theoretical research topics, we are also strongly influenced by the real-world applications such as international multimedia standards.
Our objective is to develop innovative concepts and methods for multimedia signal processing. In the past 20 years, we have conducted research in a number of fundamental and applied areas. Our research topics include MPEG Audio/Video Coding, Wavelet Video Coding, Advanced Scalable Video Coding, Motion Estimation Algorithm, and Virtual-view (Free viewpoint) Video. We participated in the international MPEG/ITU standard activities. For example, we joined the scalable video coding competition in 2004 and developed Multimedia Testbed for MPEG 21 Part 12. Our group has been successful in making significant progress on these topics and is further pursuing advanced and challenging multimedia research directions.
