Zero-block Mode Decision Algorithm for High Bit-Rate Coding in H.264/AVC

This paper proposes another zero-block inter mode decision algorithm for high bit-rate coding in H.264/AVC, to improve computation efficiency of zero-block decision. In the proposed algorithm we suggest using zero-blocks of both 8×8 and 4×4 zero-blocks to describe video sequences in detail, including global and local stationary characteristics. The experimental results reveal that significant computation improvement (up to 20% reduction) for high bit-rate coding can be achieved over the original zero-block decision algorithm.
