Research interests

I am interested in computer vision methods for people identification. I built various face recognizers and successfully evaluated them in a real world meeting room scenario. My most recent work focuses on pose invariant face recognition for a multimodal people identification system.

I previously worked on a writer independend on-line handwriting recognizer.

Research interest keywords

computer vision, human-computer interaction, pattern recognition, and visual tracking

Current Labs & Groups

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).

Current Projects [Past projects]

AAM Fitting Algorithms - Many varieties of algorithms for fitting Cootes and Taylor's "Active Appearance Models" are developed.	AAMs with Occlusion - We are developing algorithms to construct AAMs from occluded training images and to efficiently fit AAMs to faces containing occlusion.
Face Recognition - Recognizing people from images and videos.	Face Recognition Across Pose - Recognizing people from different poses.
