Abstract
Systems and techniques are provided for tracking multi joint subjects in real space having a plurality of cameras. The field of view of each camera overlaps with at least one other camera. The plurality of cameras produce respective sequences of images of corresponding fields of view in the real space. A processing system is coupled to the plurality of cameras. In one embodiment, the processing system comprises image recognition engines receiving sequence of images from the plurality of cameras and generating corresponding arrays of joint data structures. A tracking engine is configured to receive the arrays of joint data structures and generate candidate joints having coordinates in the real space. The processing system includes the logic to identify sets of candidate joints having coordinates in the real space as multi-joint subjects in the real space.
