Multimedia and Image Computing

The Department has established strong track records in the research of theory and algorithms for pattern recognition, image analysis and computer graphics that have been deployed in a variety of applications. Research by the Department's Image Computing Group (ICG) have impacted upon the respective fields. This includes in image analysis:  AI-Snake - a new form of active contour; Virtual Embryo - 3D reconstruction of entire blood vasculature of fish embryo, 3D multi-resolution statistical deformable models for liver reconstruction, I-Browse - image indexing and retrieval based on iconic and semantic content. In computer graphics, we pioneered the Body Brush, an innovative man-machine interface that combines art and technology to create a new expressive medium for artists and dancers. This technology is being applied to a new form psychotherapy called Smart Ambience Therapy (SAT). Other projects in computer graphics include the indexing and retrieval of 3D models based on machine learning techniques, and the modeling of human motion for virtual character animation.   We have also research into applications of multimedia in e-learning with projects such as Web-based English Learning System (WELS), Student Tutoring System (STS) and Personalized Education. Other projects included automatic analysis and synthesis of animation sequence for facial and hand gestures as well as computer synthesis of Chinese calligraphy, Virtual Brush. Our previous applied research in multimedia document management and workflow and virtual surgical planning have since been tech-transferred into award winning systems such as CASSOS that have been adopted by the local industries, hospitals and schools. Other projects can be found in ICG and AIMtech Centre websites.
