Description
Summary:In this paper, we provide some recent extensions to the scalable subband/wavelet video coder MC-EZBC. The enhanced MC-EZBC employs an adaptive motion-compensated temporal filter (MCTF) framework. Directional I-BLOCKs and overlapped block motion compensation (OBMC) further improve MCTF efficiency. A scalable motion vector coder based on CABAC is shown to improve the overall performance at low bitrates/resolution. Frequency rolloff is incorporated to reduce spatial aliasing at low resolution without PSNR loss at full resolution. Experimental results show that the new features significantly improve the performance of MC-EZBC. We provide several comparisons to other recent coders.
