Abstract: A method for compressing data comprising a stereoscopic pair of images which provide parallax, when viewed by left and right eyes of an observer, involves generating (S31) the stereoscopic pair of images, each image comprising a plurality of display elements. A disparity value (S32) is generated indicating an amount by which a location of each display element in a first image of the stereoscopic pair of images is displaced compared to a displaced location of the same display element in a second image of the stereoscopic pair of images, such that a plurality of disparity values is generated. The number of different disparity values present in the plurality of disparity values is then reduced (S34) to produce a reduced set of different disparity values.

Abstract: A novel multiple description coding (MDC) technique is presented whereby different side descriptions are generated with different transforms. In each of the different side descriptions, the input signal is represented by discrete values in the transform domain corresponding to the transform used in generating that description. Data fusion is then used to estimate the central description from the side descriptions.
