Research in the lab covers a broad spectrum of multimedia signal processing and analysis. In recent years, researchers in the lab have pioneered the development of feature extraction with application to image registration, segmentation, steganography and information retrieval from large multimedia databases. The researchers in the lab participate in several interdisciplinary projects including the Bio-image informatics project whose goal is to develop, test and deploy a unique, fully operational distributed digital library of bio-molecular image data accessible to researchers around the world, and the graduate training program in Interactive Digital Multimedia.
High resolution imaging of molecules and cells will be critical for understanding complex systems such as the nervous system, whether it be for the localization of specific neuron types within a region of the central nervous system, the branching pattern of dendritic trees, or the localization of molecules at the subcellular level. more...
Interactive digital multimedia involves a range of technologies and applications centered on the creation, encoding, transmission, storage, presentation, and analysis of multimedia data, as well as the study of human interaction with multimedia systems. more...
Our goal is to enable a multimedia system, i.e. an organized, easily accessible, and searchable database of large-scale amount of multimedia data. more...
The main objective is to embed as large a signature data as possible into the host signal without causing any significant perceptual distortion in the embedded signal. Steganography aims at secure undetectable communication while steganalysis aims at detecting such covert communication. Video fingerprinting aims at developing robust, compact and discriminative representations for the database videos, and is used for duplicate detection. more...
The group has developed several automated image segmentation techniques. more...
Research on image registration addresses issues related to multiscale registration, integrating robust segmentation tools with the contour matching approach, and in developing novel image representation schemes for maintaining large databases of satellite images. more...
