虚拟现实（VR）/增强现实（AR）应用允许用户在特殊应用或设备的帮助下观看模拟存在效果的周围空间的人造内容。合成内容制作是计算机图形学领域的一个众所周知的过程，其流水线在业界已经固定。然而，用于沉浸式娱乐应用的新兴多媒体格式（诸如自由视点电视（FTV）或球形全景视频）需要不同的内容管理和质量评估方法。MPEG标准推动了FTV的国际标准化。本文致力于沉浸式媒体分发格式和质量评估过程的讨论。所提出的客观质量估计方法的准确性和可靠性已被验证与球面全景图像显示良好的相关性结果与主观质量估计由一组专家举行。
Virtual reality (VR)/ augmented reality (AR) applications allow users to view artificial content of a surrounding space simulating presence effect with a help of special applications or devices. Synthetic contents production is well known process form computer graphics domain and pipeline has been already fixed in the industry. However emerging multimedia formats for immersive entertainment applications such as free-viewpoint television (FTV) or spherical panoramic video require different approaches in content management and quality assessment. The international standardization on FTV has been promoted by MPEG. This paper is dedicated to discussion of immersive media distribution format and quality estimation process. Accuracy and reliability of the proposed objective quality estimation method had been verified with spherical panoramic images demonstrating good correlation results with subjective quality estimation held by a group of experts.
