Abstract: While distributed video coding (DVC) has emerged as a new
video coding paradigm, the compression performance of current
systems is still low compared to conventional solutions
such as H.264/AVC. While the latter uses many coding modes
and an efficient mode decision strategy for choosing the best
mode, in DVC, only a limited number of modes has been developed
so far. Since encoder-side mode decision in DVC
increases encoder's complexity, in this paper, we introduce
decoder-side mode decision choosing between bitplane WZ
coding and bitplane intra coding. This strategy proves to be
efficient, delivering rate gains up to 22% over DISCOVER,
without increasing the complexity at the encoder. External Link.
