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.

Sep 14, 2010 · Thanks to MRF modeling, the global MAP estimation prob- lem for a whole image is decomposed into local MAP estimation problems for each pixel.
Jul 1, 2010 · A method to estimate the peak signal-to-noise ratio of an image performs more accurately and has a smaller estimation bias and variance ...
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.
