Abstract [en]

Inspired by the rapidly increasing popularity of 3D movies, there is an industrial push for 3DTV services to the home. One important factor for the success and acceptance by the viewers is a positive quality of experience (QoE) of the new service when delivered. The questions of how to efficiently deliver 3DTV service to the home, and how to evaluate the visual quality perceived by end users are a recent research focus. We have investigated users' experience of stereoscopic 3D video quality by preparing two subjective assessment datasets. The first dataset aimed at the evaluation of efficient transmission in the transmission error free case, while the second focused on error concealment. A total of three subjective assessments, two for first dataset and one for the second, were performed using the Absolute Category Rating with Hidden unimpaired Reference video (ACR-HR) method. The experimental setup allows to show that the ACR-HR subjective method provides repeatable results across labs and across conditions for video quality. It was also verified that MVC is more efficient than H.264 simulcast coding. Furthermore it was discovered that based on the same level of quality of experience spatial down-sampling may lead to better bitrate efficiency while temporal down-sampling is not acceptable. When network impairments occur, traditional error 2D concealment methods need to be reinvestigated as they were outperformed by displaying the same view for both eyes (switching to 2D presentation). © 2012 IEEE.

Abstract [en]

Three-Dimensional (3D) videos are using their success from cinema to home entertainmentmarkets such as TV, DVD, Blu-ray, video games, etc. The video quality isa key factor which decides the success and acceptance of a new service. Visual qualitywill have more severe consequences for 3D than for 2D videos, e.g. eye-strain,headache and nausea.This thesis addresses the stereoscopic 3D video quality of experience that can beinfluenced during the 3D video distribution chain, especially in relation to coding,transmission and display stages. The first part of the thesis concentrates upon the3D video coding and transmission quality over IP based networks. 3D video codingand transmission quality has been studied from the end-users’ point of view byintroducing different 3D video coding techniques, transmission error scenarios anderror concealment strategies. The second part of the thesis addresses the displayquality characterization. Two types of major consumer grade 3D stereoscopic displayswere investigated: glasses with active shutter (SG) technology based display,and those with passive polarization technology (film patterned retarder,FPR) baseddisplay.Themain outcomes can be summarized in three points: firstly the thesis suggeststhat a spatial down-sampling processworking togetherwith high quality video compressingis a efficient means of encoding and transmitting stereoscopic 3D videoswith an acceptable quality of experience. Secondly, this thesis has found that switchingfrom 3D to 2D is currently the best error concealment method for concealingtransmission errors in the 3D videos. Thirdly, this thesis has compared three majorvisual ergonomic parameters of stereoscopic 3D display system: crosstalk, spatialresolution and flicker visibility. The outcomes of the thesis may be of benefit for 3Dvideo industries in order to improve their technologies in relation to delivering abetter 3D quality of experience to customers.
