“…enable depth adaptation for a wide range of different 3D display devices (e.g., increasing or decreasing the depth effect as necessary) and to support multi-view autostereoscopic displays with various numbers of output views [7]. What is equally important as the employed compression technique is the transportation technique.…”

“…Hence, it was necessary to define a new framework of 3D Video (3DV) coding that is able to deliver a limited number of camera views with dense depth information to render a higher number of virtual views at high quality. Two different standardisation efforts have emerged, both exploiting cross-domain similarities in the compression cycle (i.e., multiple views and depth maps), but providing compliance with different base standards, namely MVC (such as in MVC + D [7]) and High Efficiency Video Coding (HEVC) [8], [9]. This article has been accepted for publication in a future issue of this journal, but has not been fully edited.…”

Abstract3D video is a technology that has seen a tremendous attention in the recent years. Multiview Video Coding (MVC) is an extension of the popular H.264 video coding standard and is commonly used to compress 3D videos. It offers an improvement of 20% to 50% in compression efficiency over simulcast encoding of multiview videos using the conventional H.264 video coding standard. However, there are two important problems associated with it: (i) its superior compression performance comes at the cost of significantly higher computational complexity which hampers the real-world realization of MVC encoder in applications such as 3D live broadcasting and interactive Free Viewpoint Television (FTV), and (ii) compressed 3D videos can suffer from packet loss during transmission, which can degrade the viewing quality of the 3D video at the decoder. This thesis aims to solve these problems by presenting techniques to reduce the computational complexity of the MVC encoder and by proposing a consistent error concealment technique for frame losses in 3D video transmission.The thesis first analyses the complexity of the MVC encoder. It then proposes two novel techniques to reduce the complexity of motion and disparity estimation. The first method achieves complexity reduction in the disparity estimation process by exploiting the relationship between temporal levels, type of macroblocks and search ranges while the second method achieves it by exploiting the geometrical relationship between motion and disparity vectors in stereo frames. These two methods are then combined with other state-of-the-art methods in a unique framework where gains add up. Experimental results show that the proposed low-complexity framework can reduce the encoding time of the standard MVC encoder by over 93% while maintaining similar compression efficiency performance.The addition of new View Synthesis Prediction (VSP) modes to the MVC encoding framework improve the compression efficiency of MVC. However, testing additional modes comes at the cost of increased encoding complexity. In order to reduce the encoding complexity, the thesis, next, proposes a bayesian early mode decision technique for a VSP enhanced MVC coder. It exploits the statistical similarities between the RD costs of the VSP SKIP mode in neighbouring views to terminate the mode decision process early. Results indicate that the proposed technique can reduce the encoding time of the enhanced MVC coder by over 33% at similar compression efficiency levels.Finally, compressed 3D videos are usually required to be broadcasted to a large number of users where transmission errors can lead to frame losses which can degrade the video quality at the decoder. A simple reconstruction of the lost frames can lead to inconsistent reconstruction of the 3D scene which may negatively affect the viewing experience of a user. In order to solve this problem, the thesis proposes, at the end, a consistency model for recovering frames lost during transmission. The proposed consistency model is used to evaluate...

Consistent and imitable subjective measurement 3D video quality assessment is investigated for evaluating 3D service parameters and as an essential criterion towards the development of objective models. This paper analyzes the results obtained from three test laboratories to evaluate the performance of the MVC+D and 3D-AVC 3D video coding standards using identical video content and following similar methodologies and instructions. The correlation between laboratories was investigated using similar analysis to benchmarking of objective metrics. Analyses show that test laboratories employing different displays and different subjects could still produce highly correlated results, as they follow similar guidelines to carry out assessments.
