Abstract: | For wireless multi-view video system, which has very limited capability for storage and computation at the encoder, it is
essential to design a video coding scheme with low complexity. Wyner-Ziv (WZ) coding scheme shifts large computational complexities
to decoder with side information reconstruction, however, its encoding efficiency is not high enough. To obtain higher encoding
efficiency and lower encoding complexity for wireless multi-view video applications, a network-driven low complexity video
coding method is proposed in the paper. The proposed method is designed to implement color correction, motion vector extrapolation
and disparity extraction at the central node of network, so as to reduce large computational complexities of motion estimation
at the encoder and disparity estimation at the decoder. Experimental results show that encoding efficiency of the proposed
method is higher than those of WZ coding and H.264 intraframe coding methods. The encoding complexity of the proposed method
is greatly decreased and the decoded views are of color consistency, which is favorable to high quality view rendering at
the decoder. |
