Abstract
A joint image compression system and method compress a target image and a reference image under a selected transform to produce a compressed difference image. The joint image compression system includes a computer readable media and a computer program stored on the computer readable media. The computer program includes instructions that implement selecting a transform from among a plurality of transforms that includes a subset determined projective (SDP) transform, where the selected transform minimizes a cumulative mapping error (CME) for corresponding feature points in each of a target image and a reference image. The instructions further implement applying the selected transform to one of the target image and the reference image; forming a difference image under the selected transform and compressing the difference image to produce a compressed difference image.
