This paper presented a model-based chrominance estimation algorithm in order to recover coarsely represented chrominance components in compressed color images.
This paper concerns color image restoration aiming at objective quality improvement of compressed color images in general rather than merely artifact reduction.

For each colour model, each image was compressed to. 4 different levels, or quality factors. For a lower quality factor, a higher compression ratio was applied.
