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.

A method for identifying objects in a sequence of images, comprising:
- receiving the sequence of images recorded using a camera having a field of view;
- detecting regions of interest in the sequence of images including at least some the objects;
- locating in the detected regions of interest encoded transmissions from active devices positioned in the field of view of the camera;
- outputting the sequence of images while identifying at least some of the regions of interest using encoded transmission identified therein.
A method for identifying objects in a sequence of images, comprising:
- receiving the sequence of images recorded using a camera having a field of view;
- receiving motion information from active devices in the field of view of the camera;
- detecting regions of interest in the sequence of images including at least some the objects;
- associating the movement information from the active devices with the movement of the detected regions of interest between images in the sequence of images;
- outputting the sequence of images while identifying at least some of the regions of interest using the motion information.
