Abstract :
While monocular gesture recognition slowly reaches maturity, the inclusion of 3D gestures remains a challenge. In order to enable robust and versatile depth-enabled gestures, a depth-image based tracking approach is developed. Using a model-based annealing particle filter approach, the pose of a single subject is retrieved and tracked over longer image and motion sequences. Other than many previous depth-image based systems, full body tracking is performed. The system is independent from specific camera types and is independent from color or texture cues. Pose space exploration in complex kinematic chains is enhanced by considering extending inverse kinematics. Exploiting the highly parallel nature of the 3D point based approach, the algorithm is partially implemented on a GPU, leading to near real time performance.
