Research interests

I develop vision algorithms that can track targets, recover camera motion and 3D scene simultaneousely. I am especially interested in making the algorithms robust against occlusions and abrupt camera motions. The strength of my approach lies on the faithful representation of the uncertainty in the vision algorithms. For more results, please check my personal web page.

After an internship in NEC USA Corp., I became very interested in high dimensional multi-media data mining and knowledge discovery problem.

Research interest keywords

computer vision, pattern recognition, and visual tracking

Past Projects

Tactical Mobile Robotics - As part of the DARPA Tactial Mobile Robotics program, we are developing techniques for semi-autonomous navigation of a small robot in urban environments.

Unmanned Ground Vehicles - Developing autonomous navigation capabilities for mobile robots driving in complex, unstructured outdoor terrain.
