In current distributed video coding (DVC) issues, the huge computational complexity caused at the decoder has not been sufficiently discussed. This paper proposes a mixed resolution DVC based on selective data pruning to improve coding performance with less complexity at the decoder. Mixed resolution framework is based on full resolution key frames and spatial-reduction-based non-key frames. The selective data pruning is considered as a better side-information generation than normal scaling. We also adapt nonlinear quantization for residual coding on the transform domain Wyner-Ziv coding to minimize the entropy of the interpolated pixels. Experimental results show the proposed method outperforms a conventional DVC for sequences with a large amount of motions and it is also suitable for large GOP structure. |
