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)
