Paper Abstract

A novel image improving algorithm for compressed image sequence by blending with reference images is presented. The reference image is defined as the high quality still image of the same scene. Compressed images are improved by blending the data directly with the reference image in both DCT and spatial domain. Amount of blending is controlled by the resemblance between the reference and the compressed image. Experiments conducted on the sequence of H.263 compressed image is presented. Prior information about compression technique is not required so this technique should be able to apply to other techniques as well.
