Current Research
Human Action Localization and Recognition
Developed a fast action recognition system achieving state of the art performance on two public datasets. (ongoing work)
Human Detection and Pose Segmentation
Introduced a pose-adaptive descriptor for simultaneous human detection and pose segmentation. (see our ECCV 2008 paper for details)
Appearance Matching and Recognition
Developed pairwise discriminative learning-based techniques to appearance-based person recognition to better handle the scalability
problem, i.e. recognition of large number of categories. Also developed algorithms for matching appearances under occlusion. The approach
is tested on 61 person Honeywell appearance dataset, and 50 person multiview, multipose Keck lab (UMD) dataset.
Part of this work is delivered to Panasonic Inc. Princeton, NJ
Multiple Occluded Human Detection, Segmentation and Tracking
Developed algorithms for detecting and segmenting humans under occlusion. The detection
is performed by a part-template shape matching method and the segmentation is done by
pose-assisted appearance-based segmentation which simultaneously estimates human poses and
segmentation. We are currently applying these approaches to multi-target tracking system for
visual surveillance applications.
