Another approach to tracking a specific object with a 400 Series camera is to attach image tags called Aruco markers to the surface of the object so that the camera can detect the tag and capture the object's "pose" (its position and rotation). Add color keying support for the PT tracker: you can now track plain colors (by @a1k0n). The results for the object tracking benchmark (OTB) [12,13] and visual object tracking (VOT) [14,15] show that discriminant tracking algorithms are superior to generative tracking algorithms in.
