Patent 7593465 was granted and assigned to LSI Corporation on September, 2009 by the United States Patent and Trademark Office.
A method and circuit for processing a reconstructed picture generated from compressed data is disclosed. The method generally includes the steps of (A) estimating a magnitude of coding artifacts created by a coding process for the compressed data based upon the compressed data, (B) generating a plurality of noise samples with a probability distribution over a range, the probability distribution determined by the magnitude and (C) adding the noise samples to the reconstructed picture for concealment of the coding artifacts.
