Complement to networking and communication research for which the focus is efficient information delivery, our multimedia research concentrates mostly on efficient information processing. The explosive growth of multimedia information over the Internet makes it an urgent task to develop automatic systems for intelligent processing of the vast amount of multimedia data. Toward this goal, multimedia research in the Department of Information Engineering focuses mostly on intelligent processing of image, video, and computer graphics. Current research topics range from image and video indexing and retrieval, image and video based biometrics, video based character recognition, to 3D graphics. Representative research projects include Chinese News Video Retrieval Engine, Automatic Face Recognition, Video-based Chinese Character Recognition, and 3D Object Reconstruction from Single 2D Line Drawings
