Research on light field camera and music emotion recognition

In this talk, I will give a presentation of some recent progress we have made at the Multimedia Processing and Communications Lab of National Taiwan University. Specifically, I will describe the multimedia signal processing techniques we have developed for applications to digital video camera and emotion-based multimedia presentation. The demos to be shown in this talk include 1) programmable aperture photography: multiplexed light field acquisition, 2) music emotion recognition for multimedia retrieval and presentation, 3) integration of video stabilizer with digital video codec, 4) auto focusing, 5) auto white balance, 6) color transfer, and 7) Wii-like 3D pointer.
