Objective assessment of stereoscopic video quality of 3DTV. (Évaluation objective de la qualité vidéo en TV 3D relief)

چکیده
The minimum requirement for any 3D (stereoscopic images) system is to guarantee visualcomfort of viewers. Visual comfort is one of the three primary perceptual attributes of 3DQoE, which can be linked directly with technical parameters of a 3D system. Therefore,the goal of this thesis is to characterize objectively the impact of these parameters onhuman perception for stereoscopic quality monitoring.The first part of the thesis investigates whether visual attention of the viewers shouldbe considered when designing an objective 3D quality metrics. First, the visual attentionin 2D and 3D is compared using simple test patterns. The conclusions of this firstexperiment are validated using complex stimuli with crossed and uncrossed disparities.In addition, we explore the impact of visual discomfort caused by excessive disparitieson visual attention.The second part of the thesis is dedicated to the design of an objective model of 3Dvideo QoE, which is based on human perceptual thresholds and acceptability level. Ad-ditionally we explore the possibility to use the proposed model as a new subjective scale.For the validation of proposed model, subjective experiments with fully controlled stilland moving stereoscopic images with different types of view asymmetries are conducted.The performance is evaluated by comparing objective predictions with subjective scoresfor various levels of view discrepancies which might provoke visual discomfort.

Visual quality assessment of synthesized views in the context of 3D-TV
DIBR is fundamental to 3DTV applications because the generation of new viewpoints is recurrent. As any tool, DIBR methods are subject to evaluations thanks to the assessment of the visual quality of the resulting generated views. This assessment task is peculiar because DIBR can be used for different 3DTV applications: either in a 2D context (free viewpoint video), or in a 3D context (3D displa...

3D video is new media extension of conventional 2D video into third dimension adding depth sensation and resolving 2D viewing ambiguity. Stereoscopic and free-viewpoint videos are visual representation and coding formats which takes 3D geometry information of acquisition system. Different 3D video acquisition, processing and representation technologies can be used, but all make use of multiple ...
متن کاملThree-dimensional Television: From Science-fiction to Reality
Moving three-dimensional images have been depicted in many science-fiction films. This has contributed to 3D video and 3D television (3DTV) to be perceived as ultimate goals in imaging and television technology. This vision of 3DTV involves a ghost-like, yet high quality optical replica of an object that is visually indistinguishable from the original (except perhaps in size). These moving vide...
متن کاملVAAL, Video Adaptation at Application Layer and Experiments using DCCP
More and more high definition and high quality videos are nowadays stored on Internet but they are not accessible for everybody because high and stable bandwidth is needed to stream them. A lower bitrate encoding is usually chosen but it leads to lower quality too. A solution is to use a TCP-friendly transport protocol and let the application itself choose for each user the bitrate of the video...
