摘要：The quality of digital images recovered from compressed data in an inter-frameredundancy-removing scheme is enhanced using a self-adaptive feedback scheme in animage compression/decompression system so as to include means for the compensation

of the distortion component from prior frame compression in subsequent differenceframe compression. Each transmitted frame is stored after a full compress/decompresscycle, and difference data (which includes the inverse of the distortion component fromcompression of the transmitted frame) representing the difference between the storedframe and the incoming new frame is transmitted. Consequently, the quality of staticregions in the recovered images may be improved with each subsequent iteration bytaking the distortion component in the prior frame into consideration along with theinter-frame motion information. The feedback loop thus forms a self-adaptive iterativecycle.
