My research interests are in the areas of Computer Vision, Pattern Recognition, Computer Animation, Human Computer Interaction, Machine Learning, Medical Image Processing, and Robotics. I am currently working on non-rigid object shape and motion recovery from video, deformable shape registration and modeling, 3D shape reconstruction and modeling of human faces, real-time 2D/3D visual tracking, facial expression recognition, and facial animation. Prior to these works, my research topics included feature grouping and object detection, image segmentation, image enhancement, and automatic control.

animation, computer vision, human-computer interaction, machine learning, medical imaging, and object recognition

• Face Group - Robust detection, recognition, and tracking of human faces with automated analysis of expressions
• Human Identification at a Distance - We are developing and evaluating human identification technologies as part of the Defense Advanced Research Projects Agency (DARPA) sponsored program in Human Identification at a Distance (HumanID).

• 2D->3D Face Model Construction - We develop a linear algorithm that uniquely recovers the 3D non-rigid shapes and poses of a human face from a 2D monocular video.
• 3D Head Motion Recovery in Real Time - A cylindrical model-based algorithm recovers the full motion (3D rotations and 3D translations) of the head in real time.
• AAM Fitting Algorithms - Many varieties of algorithms for fitting Cootes and Taylor's "Active Appearance Models" are developed.
• Face and Facial Feature Tracking - Rigid Tracking of Faces and Non-Rigid Tracking of Facial Features
• Face Model Building and Fitting - Techniques for building and fitting 2D and 3D models of human faces and heads.
• Facial Expression Analysis - Automatic facial expression encoding, extraction and recognition, and expression intensity estimation for the applications of MPEG4 application: teleconferencing, human-computer interaction/interface.
