Abstract (in Japanese) (See Japanese page) 
(in English) 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.
