Abstract

We propose a novel method for moving picture coding by wavelet transform and an edge adaptive deblocking filter. In order to reduce the blocking distortion, we apply wavelet coding with discrete wavelet transform (DWT) and set partitioning in hierarchical trees (SPIHT) to coding of I-picture and the difference image. The blocking distortion caused by block motion compensated prediction is reduced by an edge adaptive deblocking filter. Since wavelet coding has no blocking distortion, the original edges in the image can be detected precisely and an edge adaptive deblocking filter is very effective. Experimental results show that blocking distortion has been reduced at very low bit rate coding. Better peak-to-peak signal-to-noise ratio (PSNR) values in about 2 dB for both I-pictures and P-pictures have been achieved compared to MPEG2, coding.
