  • Abstract
    A global motion compensation (GMC) scheme is described and implemented for low bitrate coding. Experiments show that GMC gives excellent coding results. When coupled with the H.263 low bitrate video coding standard, GMC is capable of achieving up to 27% bitrate saving (or 1.8 dB gain in PSNR) for a high motion sequence such as Stefan. For a moderate motion sequence such as Cost-guard, we obtained an 8% bitrate saving over H.263 at the same quality using GMC
