    Abstract

    Fast mode selection is one of the hottest research
    topics for H.264/AVC finalized in 2003. Since the computational
    complexity is still a major challenge for real-time applications,
    simplification of mode selection is therefore very important. A
    fast mode selection algorithm is proposed in this paper. By
    removing low-probability modes according to the correlative
    characteristic in macroblock mode selection and the statistical
    characteristic of sub-macroblock mode selection, the calculation
    of mode selection process is significantly reduced. Based on the
    experimental results, the encoding time can be saved 55.91% on
    average, and in most cases the degradation of video quality is
    limited in 0.15dB with less than 2% increase of bitrate.
