Abstract
H.264 processes more detailed and more motion information for the compression efficiency. However, motion vector of H.264 takes more portion than previous standards such as MPEG-1/2/4 do, so that it is needed to consider motion vectors. This paper proposes the new algorithm with leaf mode in order to compress the motion vector efficiently. The proposed algorithm concentrates modes' distribution with leaf mode and carries out the compression of motion vector with less modes. The proposed algorithm adopted in current $4{\times}4$ motion vector matrix also can be extend to $8{\times}8$. The experiments shows that the proposed algorithm reduces up to 12.68% at header and 9.7% at resultant bitstream.
