Abstract

This study aims to remove blocking distortions in compressed moving pictures. We propose to apply sub-band transform (ST) and an edge adaptive deblocking filter to remove the blocking distortions caused by transforms and the block motion compensated prediction in moving picture coding, respectively. We evaluate coding efficiency and distortion level experimentally by PSNR value and subjectively through visual appearance. It give good PSNR values compared to the discrete cosine transform (DCT) and the discrete wavelet transform (DWT). The edge adaptive deblocking filter produced an improved quality of the decoded pictures. The ST with an edge adaptive deblocking filter is an efficient way to decode pictures and proves from the PSNR values and the quality of pictures.
