The Multimedia Processing and Communications (MPAC) Lab, led by Professor Homer H. Chen of the Graduate Institute of Communication Engineering (GICE) at National Taiwan University, is engaged in the development of cutting-edge technologies for digital audio/video signal analysis and synthesis, digital video coding, image processing, media streaming, and multimedia systems. Our target applications include digital still camera, digital video camera, LCD display, digital home, P2P content delivery network, IPTV, DTV, video surveillance, and multimedia information retrieval. Our mission is to develop core technology for real-world problems and to give students the world-class engineering training.
