TL;DR: A novel complexity reduction method is proposed that takes advantage of the relationship between disparity vectors along time and results in saving up to 93% in encoding time at the cost of only 0.08 dB in peak signal-to-noise ratio (PSNR) and 1.64% increase in bitrate compared to the standard MVC implementation (JMVM 6.0).

Abstract: We consider the problem of complexity reduction in Multiview Video Coding (MVC). We provide a unique comprehensive study that integrates and compares the different low complexity encoding techniques that have been proposed at different levels of the MVC system. In addition, we propose a novel complexity reduction method that takes advantage of the relationship between disparity vectors along time. The relationship is exploited with respect to the motion activity in the frame, as well as with the position of the frame in the Group of Pictures. We integrate this technique into our unique comprehensive framework and evaluate the performance of the resulting system in different setups. We show that the effective combination of complexity reduction techniques results in saving up to 93% in encoding time at the cost of only 0.08 dB in peak signal-to-noise ratio (PSNR) and 1.64% increase in bitrate compared to the standard MVC implementation (JMVM 6.0).

TL;DR: A new hybrid motion vector extrapolation (HMVE) algorithm is proposed to recover the whole missing frame and it is able to provide more accurate estimation for the motion vectors of the missing frame than other conventional methods.
Fast encoding techniques for Multiview Video Coding
TL;DR: A complete low complexity MVC encoding solution that combines two new methods with complementary previous methods to speed up motion and disparity search and can reduce the encoding time and number of search points of the standard MVC implementation (JMVM 6.0).

TL;DR: Experimental results show that, compared to reference software JMVM 5.1, the average time reduction is 86.63% while the bitrate increase and PSNR loss are less than 0.20% and 0.02 dB, respectively.

Fast Encoder Design for Multi-view Video
TL;DR: This paper presents a fast encoder design to reduce the level of complexity of multi-view video coding, which employs macroblock-based inter-view prediction when the temporal correlation of a group of pictures is sufficiently strong and when the disparity between two adjacent views is above some threshold.
