The methods that improve restored graphic data quality based on their representations with the high compress level are reviewed. The method of negative influence removing of the edge Gibbs’s effect based on local compression degree decrease of specific compressed images zones was made. For blocking effects suppression the interpolation method based on edge detection of separate color picture object with subsequent decomposition and smoothing procedure is proposed. The results of subjective evaluation of restored images quality are adduced.
