Reduction of Blocking Artifacts in Block Transformed Compressed Color Images

In this paper we use the information in the chrominance bands to reconstruct color block transformed compressed images. For the luminance and the two chrominance channels, we de ne a reconstruction problem and show how to estimate the unknown hyperparameters and reconstruct each band automatically. The method is tested on real images.
