Research interests

My research is in wireless sensor networks and computer vision. I am currently working on using many networked low-level sensors to answer high-level queries in a distributed way. Specifically, I am interested in using cameras in the energy constrained wireless sensor network environment, where computation and communication are limited. Cameras are high data rate devices, so the data must be aggregated as early and as much as possible. One of the aspects I seek to understand is the tradeoff between communication and computation in a camera network. Another aspect is to understand what can be sensed with a camera network composed of hundreds or thousands of camera nodes. On the computer vision side, I have worked on tracking non-rigid objects and determining structure from motion.
