This is a video of a monocular (that's one camera) 3D tracking system. The tracking is based on the Bayesian Occupancy Filter with some creative usage of its parameters allowing us to get depth estimation. The system uses one webcam (a Logitech PRO 9000) for detecting and tracking the blue ball, which then is used for depth estimation.
This demo here is using the monocular tracker system integrated into an application named Gesture Therapy. This application is used for patient rehabilitation after a stroke.
Other applications include human-machine interface, augmented reality, virtual reality, ...
Lots of thanks to the guys at Probayes, INRIA and INAOE!
