My research interests are in articulated body pose estimation and human activity recognition from image data. Using grayscale, color, LWIR thermal images arriving in single, stereo, or multiple perspective sets, the problem is to learn the articulated body structure, body pose, gesture and activity of the imaged subject. Oftentimes, applications do not require the fidelity of a full body model. Smart airbag systems which sense the occupant's posture in the vehicle to modulate airbag deployment response for example require only the pose of the upper body, or the head and torso. It is also important to examine the operating conditions as part of the problem. For that, I am interested in Intelligent Vehicle, Intelligent Transportation Systems areas as an application for these ideas. Comments and suggestions are always welcome.
