My research team at the Multimedia Processing and Communications (MPAC) Laboratory, National Taiwan University, has been engaged in a variety of research projects related to the processing and communication of multimedia signals, with applications to digital video camera, P2P IPTV, digital home, and music information retrieval. In this talk, I will first briefly introduce our research projects in the area of music emotion recognition and perception inspired video processing through a series of demos. Then I will zoom in on our recent work on computational imaging, in particular, digital autofocus and light field acquisition. The former, which is fundamental to digital cameras and digital video camcorder, is by no means an easy problem. It eventually led us to an alternative solution involving light field acquisition. The latter is about a programmable aperture technique that exploits the fast multiple-exposure feature of digital sensors without trading off the sensor resolution and without moving the camera in the light field acquisition process. I will then conclude the talk by highlighting the challenges of super resolution light field rendering.


Homer H. Chen (M'86-SM'01-F'03) received the Ph.D. degree in Electrical and Computer Engineering from University of Illinois at Urbana-Champaign.

Dr. Chen is a renowned expert in multimedia signal processing and communications. His professional career has spanned across academia and industry. Since August 2003, he has been with the College of Electrical Engineering and Computer Science, National Taiwan University, where he is Irving T. Ho Chair Professor. Prior to that, he held various R&D management and engineering positions with U.S. companies over a period of 17 years, including AT&T Bell Labs, Rockwell Science Center, iVast, and Digital Island (acquired by Cable & Wireless). He was a U.S. delegate for ISO and ITU standards committees and contributed to the development of many new interactive multimedia technologies that are now part of the MPEG-4 and JPEG-2000 standards. His professional interests lie in the broad area of multimedia signal processing and communications.

Dr. Chen is an IEEE Fellow. As a Technical Program Co-Chair, he helped revamp the IEEE International Conference on Multimedia and Expo in 2010. He was an Associate Editor of IEEE Transactions on Circuits and Systems for Video Technology from 2004 to 2010, IEEE Transactions on Image Processing from 1992 to 1994, and Pattern Recognition from 1989 to 1999. He served as a Guest Editor for IEEE Transactions on Circuits and Systems for Video Technology in 1999 and for IEEE Transactions on Multimedia in 2011.
