Abstract
Methods are disclosed for augmenting the identification of objects tracked in a sequence of images using active devices. In one embodiment, encoded information transmitted from active devices, such as a PDA, is decoded from the sequence of images to provide identifying information to a tracked region of interest. In another embodiment, motion information transmitted from active devices is associated with regions of interest tracked between images in the sequence of images. In a further embodiment, these embodiments operate together to minimize possible signal interference.
