Abstract
A method and system for creating a depth signature from plural images for providing watermark information related to the images. The method comprises analyzing a pair of images, each image containing a plurality of elements, identifying a first element in one of the pair of images, identifying plural elements in the other of the pair of images. The method further comprises measuring a disparity parameter between the first element and a set of the plural elements, matching the first element from the set of plural elements, the matched second element having the smallest measured disparity parameter, and computing a signature based at least in part on the measured disparity between the first and second elements.
