FORTH 3D Human Body Tracker

We present results of our work on a method for tracking a 3D skeletal model of the human body based on markerless observations acquired by a single RGBD camera. The proposed approach has a number of attractive properties, such as: - It tracks a skeletal model of the human body (torso, arms, legs) plus the fingers of hands - It tolerates differences in biometrics, clothing, distance of observation, illumination variations - It handles occlusions (e.g., body occluded by objects, partial body views) - It performs automatic initialization / re-initialization, automatic recovery from tracking failures - It provides information on limbs depending on confidence - It operates with a potentially moving camera - It performs in real time (20-30 fps) on a conventional processor (single CPU, no GPGPU) D.
