I am interested in both general methodologies and real-life applications of the following fields:
Computer vison, image and video understanding;
AI, statistical inference and learning;
Computer graphics and computer animation;
Image processing and pattern recognition;
Human vision and biologically motivated vision.
Object tracking and association from a network of video cameras for wide-area surveillance.
Human segmentation and tracking in monocular video streams:
Segmentation and tracking of multiple humans in complex situations where people move in a small group, have inter-occlusion, cast shadows, etc.
Stochastic segmenation of multiple humans in crowded situations.
Tracking of multiple humans in crowded situtations.
A tracking as recognition framework to track human motion (an example on human locomotion).
A flexible method to calibrate a (surveillance) camera.
A language-based representation for spatial visual events.
Learning highly structured motion model (concept) of human motion.
Tracking human arms in 3D from monocular video stream.
Car detection in aerial images.
