Identifying objects tracked in images using active device
First Claim
Patent Images
1. 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.

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.
