Abstract
Transform Domain Wyner-Ziv (TDWZ) video
coding is an efficient Distributed Video coding solution providing
new features such as low complexity encoding, by mainly
exploiting the source statistics at the decoder based on the
availability of decoder side information. The accuracy of the
decoder side information has a major impact on the performance
of TDWZ. In this paper, a novel multi-hypothesis based TDWZ
video coding is presented to exploit the redundancy between
multiple side information and the source information. The
decoder used optical flow for side information calculation.
Compared with the best available single estimation mode TDWZ,
the proposed multi-hypothesis based TDWZ achieves robustly
better Rate-Distortion (RD) performance and the overall
improvement is up to 0.6 dB at high bitrate and up to 2 dB
compared with the DISCOVER TDWZ video codec.
