Abstract

A novel hybrid frequency and spatial domain method is presented for blockiness reduction in low bit rate compressed images. The proposed method consists of two stages acting complementarily. In the first, better estimates of the reconstructed DCT coefficients are obtained based on their observed probability distribution. In the second, an efficient postprocessing scheme, consisting of a region classification algorithm and spatial adaptive filtering, is applied. Experimental results illustrating the performance of the proposed method are presented and evaluated.
