Abstract :
This paper presents a new algorithm for reducing aliasing artifacts related to the conventional spatial scalable subband/wavelet coding for recovering video at lower resolution. The proposed scheme has been fully integrated with the H.264/AVC JSVM reference software and experimentally evaluated against the conventional methods for intraframe spatial scalable video coding. The simulation results show our method can effectively remove the aliasing artifacts for scalable decoding at lower resolution without performance penalty at full resolution.
