TLDR
A flexible MVC structure which can satisfy different bit rate requirements and an adaptive SI selection mechanism which better utilizes temporal and interview correlations to obtain more accurate SI are proposed.Abstract:
A GOP-flexible multiview video coding (MVC) scheme based on Wyner-Ziv (WZ) coding with adaptive side information (SI) is proposed in this paper. In this scheme, each view is WZ encoded independently at the encoder side, while the views are jointly decoded at the decoder side. Therefore, the communications of different cameras can be avoided at the encoder side. In WZ coding, SPIHT and LDPC are applied to improve compression efficiency. Meanwhile, a flexible MVC structure which can satisfy different bit rate requirements and an adaptive SI selection mechanism which better utilizes temporal and interview correlations to obtain more accurate SI are proposed. The experimental results show better rate-distortion performance of the proposed scheme than other tested schemes.read more

A framework for multi-view video coding using layered depth images
TL;DR: In this article, a framework for multi-view video coding using the concept of layered depth image (LDI) is presented. But the LDI technique is not suitable for the multiview video data, since the data size of the multiview video linearly increases as the number of cameras.
