  Abstract

In H 264, 7 modes {16×16, 16×8, 8×16, 8×8, 8×4, 4×8, 4×4} are used to enhance the coding efficiency. The motion vector estimation with 7 modes may requrie huge computing time. In this paper, to speed up the motion vector estimation procedure while the high image quality remains, we propose a motion vector refinement scheme using the temporary motion vector generated with little computation. The proposed estimation process consists of three phases. Mode decision for a 16×16 macroblock, Composing a temporary motion vector, Refinement of the temporary motion vector. We demonstrate the effectiveness of the proposed method by computer simulation. In the results, the encoding time consumed by the proposed scheme has been reduced significantly while the encoded video quality remains unchanged.
