An efficient low-delay multi-view distributed video coding

Distributed video coding(DVC)is a video coding solution for shifting coding complexity from encoder to decoder. Multi-view distributed video coding(MDVC)mainly uses the motion compensation interpolation(MCI)to reduce the temporal redundancies inside the viewpoint. But the decoding order of MCI is inconsistent with the video sequence, which leads to decoding delay. Based on motion compensation extrapolation(MCE), an efficient low-delay MDVC was proposed. In addition, the general MCE reconstruction quality is lower than that of the MCI method. On the basis of the MCE, the disparity vector interpolation was employed to reduce the interview redundancies, while fusion algorithm was applied to improve the reconstruction quality. Results show that the decoding time of the presented method is reduced by 0.3 s in the case of reconstruction quality of equal quality. © 2015, Tianjin University. All right reserved.
