Research interests

The word "multimedia" is more than the simple combination of text, audio, images, graphics and video. The interaction among these media, and their interaction with humans, networks, and storage media, are what really make multimedia research exciting. Our research group, the Advanced Multimedia Processing (AMP) Lab, has wide interests in various techniques for multimedia applications. Our current research topics include:

Computer Vision and Pattern Recognition: object detection and tracking, 3D reconstruction, video surveillance, 3D object retrieval and streaming, combined vision and inertia sensing

Computer Graphics: multiview imaging, image-based rendering, illumination normalization and relighting

Multimedia Coding and Streaming: video over wireless, rate shaping/control, traffic/channel modeling, encoder optimization, and error concealment

Multimodal Biometrics: face tracking, face recognition, voice identification, and lip-reading

System Implementation: hardware-software implementation of speech recognition systems and multimedia codecs

Bioinformatics: Analysis and matching of 3D protein structures

Research interest keywords

acoustics, animation, computer graphics, computer vision, data visualization, gesture recognition, graphics, human-computer interaction, image compression, image processing, object recognition, pattern recognition, sensor fusion, video systems, and visual tracking

Current Labs & Groups

Face Group - Robust detection, recognition, and tracking of human faces with automated analysis of expressions

Past Projects

Personal Robotic Assistants For The Elderly - Pearl will help researchers explore the ways autonomous mobile robots can help the elderly live independently in their own homes.
