Abstract: Abstract: For video coding standards with high compression ratio and
good image quality, prediction is an essential step. If the prediction
is more accurate, then lower bit-rate will be achieved.
In this paper, a method is proposed to improve the coding
efficiency for motion vectors using predicted motion vector
candidate set (PMVCS). PMVCS consists of the motion vectors
of blocks, which are the spatial and temporal neighbors
of an encoding block. Using the proposed method, a better
predicted motion vector can be obtained, which will result
in fewer bits allocated for motion vectors. Compared with
JIM18.4, the proposed method can reduce the bit allocation for
motion vectors by 1.37% in average using the image sequence
“Bus.” The proposed method can reduce the bit allocation for
motion vector of error correction technique by about 0.31%
using the same image sequence.
