Abstract:

Multimedia Signal Processing plays an important role in the digital archives development process. Multimedia covers different kinds of media, including video, image, audio, and 3D graphics. In this talk, I will present some basic issues regarding video retrieval and 3D graphics retrieval. For video retrieval, we extract some statistics-based features from videos and then perform quick retrieval.  For video-based event detection, on the other hand, we compute corresponding trajectories from videos and then execute efficient event detection.  For 3D-graphics retrieval, we propose a visual salience-guided 3D mesh decomposition approach which is able to perform top-town mesh decomposition.  The decomposed salient parts of 3D objects can be used to execute fast retrieval.  In addition to the theoretical issues of the above topics, their potential applications that may be useful in the fields of surveillance, security, and entertainment will also be addressed.

Biography:

Hong-Yuan Mark Liao received a BS degree in physics from National Tsing-Hua University, Hsin-Chu, Taiwan, in 1981, and an MS and Ph.D degree in electrical engineering from Northwestern University, Evanston, IL, in 1985 and 1990, respectively.

He was a Research Associate with the Computer Vision and Image Processing Laboratory at Northwestern University during 1990-1991. In July 1991, he joined the Institute of Information Science, Academia, Sinica, Taipei, Taiwan, as an Assistant Research fellow. He was promoted to Associate Research Fellow and then Research Fellow in 1995 and 1998, respectively.  From August 1997 to July 2000, he served as the Deputy Director of the institute. From Feb. 2001 to Jan. 2004, he served as the Acting Director of the Institute of Applied Science and Engineering Research. Currently, he is the director of the Academia Sinica Computing Center.  He is also jointly appointed as a professor of the Computer Science and Information Engineering Department  of National Chiao-Tung University. His current research interests include multimedia signal processing, video-based Surveillance Systems, content-based multimedia retrieval, and multimedia protection. He is now the Managing Editor of the Journal of Information Science and Engineering. He is on the editorial boards of the International Journal of Visual Communication and Image Representation, EURASIP Journal on Applied Signal Processing, and the Tamkang Journal of Science and Engineering. He was an associate editor of IEEE Transactions on Multimedia during 1998-2001.  Currently, he serves as a member of the Multimedia Signal Processing Technical Committee of the IEEE Signal Processing Society.

Dr. Liao was the recipient of the Young Investigators' award from Academia Sinica in 1998; the Excellent Paper Award from the Image Processing and Pattern Recognition society of Taiwan in 1998 and 2000. He received the Distinguished research award from the National Science Council of Taiwan in 2003 and the National Invention Award of Taiwan in 2004. He served as the Program Chair of the International Symposium on Multimedia Information Processing（ISMIP’97）and the Program co-chair of the Second IEEE Pacific-Rim conference on Multimedia（2001）. In June 2004, he served as the conference co-chair of the 5th International Conference on Multimedia and Exposition (ICME).  Dr. Liao served as Program Co-Chair of 2005 and 2006 IEEE International Symposium on Multimedia, and will serve as a program co-chair of 2007 IEEE International Conference on Multimedia and Exposition (ICME).
