With the proliferation of mobile video cameras, users can now easily capture videos of live performances and socially share them with friends and public. As an attendee of such live performances typically has limited mobility, each video camera is able to capture only from a range of restricted viewing angles and distance, producing a rather monotonous video clip. At such performances, however, videos are captured by multiple users, likely from different angles and distances. These videos can be combined to produce a more interesting and representative mashup of the live performances for broadcasting and sharing. In this work, we present MoViMash, a framework for automatic online video mashup that makes smooth shot transitions to cover the performance from diverse perspectives. Shot transition and shot length distributions are learned from professionally edited videos. Further, we introduce view quality assessment in the framework to filter out shaky, occluded, and tilted videos.
CS3283/4 is a 2-semester project class where students work in teams to build cool applications, applying sound software engineering practices and principles.
I have also previously taught CS2105, an introductory course on computer networking, CS4344, an advanced course on networking and systems support for multi-player games, CS5229, a graduate-level course where we look into classic papers on the Internet, and CS2106 an introductory undergraduate course on operating systems.

I received my B. Sc. (Hon.) degree from the Department of Information Systems and Computer Science (now School of Computing), NUS in 1996, and Ph. D. from Cornell University, Ithaca, NY in 2001. I spent a year as postdoc at Berkeley Multimedia Research Center in U.C. Berkeley, before re-joining NUS in 2002. I came from Alor Setar, Malaysia.
