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.
