Conversion of free-viewpoint 3DTV signals for stereo displays

چکیده
This paper presents our ongoing research on view synthesis of free-viewpoint 3D video for 3DTV. First we describe our rendering algorithm developed for autostereoscopic viewing of multi-view 3D video. Then we present two solutions for converting free-viewpoint 3D into a stereoscopic vision, while taking into account the complexity of the algorithms since we aim at a real-time hardware implementation. We conclude with the first evaluations of the algorithm and a discussion of the obtained results.

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...
متن کاملNew Requirements of Subjective Video Quality Assessment Methodologies for 3dtv
In this paper, the new challenges of 3DTV for subjective assessment are discussed. Conventional 2D methods have severe limitations which will be revealed. Based on the understanding of the new characteristics brought by 3DTV, changes and additions in the requirements for subjective assessment are proposed in order to develop a novel subjective video quality assessment methodology for 3DTV. In p...
متن کاملMobile 3DTV System: Quality and User Perspective
While mobile 3DTV system components such as stereo video compression techniques, transmission channels and autostereoscopic displays are available and with good level of maturity, their joint work crucially depend on the quality and user acceptance. We address these two key factors by rigorously investigating all possible artifacts appearing at all processing stages and influencing different la...
متن کاملA Flexible Client-Driven 3DTV System for Real-Time Acquisition, Transmission, and Display of Dynamic Scenes
3D experience and free-viewpoint navigation are expected to be two essential features of next generation television. In this paper, we present a flexible 3DTV system in which multiview video streams are captured, compressed, transmitted, and finally converted to high-quality 3D video in real time. Our system consists of an 8 × 8 camera array, 16 producer PCs, a streaming server, multiple client...
متن کاملTrend and challenges in 3D digital television: video formats and transmission standards
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 ...
