摘要翻译:
增加3d视频的帧率通常导致改善的体验质量(QoE)。然而,更高的帧速率涉及捕获、传输、存储和显示的更高程度的复杂性。这里出现的问题是,在现有/所需的3D设备和技术(3D摄像机、3D电视、压缩、传输带宽和存储容量)的情况下,什么帧率能保证高观看质量的体验。这个问题已经在2D视频的情况下得到了解决,但在3D视频的情况下没有得到解决。本文的目的是研究不同帧率下的三维质量与比特率之间的关系。我们的性能评估表明,将3D视频的帧率提高到60 fps以上可能无法在视觉上区分。此外,我们的实验表明,当可用带宽减少时,可以通过调整(降低)帧率而不是提高压缩比来获得最高的3D体验质量。我们的研究结果对于变比特率信道中的速率自适应网络提供商特别感兴趣。

英文摘要:
Increasing the frame rate of a 3D video generally results in improved Quality of Experience (QoE). However, higher frame rates involve a higher degree of complexity in capturing, transmission, storage, and display. The question that arises here is what frame rate guarantees high viewing quality of experience given the existing/required 3D devices and technologies (3D cameras, 3D TVs, compression, transmission bandwidth, and storage capacity). This question has already been addressed for the case of 2D video, but not for 3D. The objective of this paper is to study the relationship between 3D quality and bitrate at different frame rates. Our performance evaluations show that increasing the frame rate of 3D videos beyond 60 fps may not be visually distinguishable. In addition, our experiments show that when the available bandwidth is reduced, the highest possible 3D quality of experience can be achieved by adjusting (decreasing) the frame rate instead of increasing the compression ratio. The results of our study are of particular interest to network providers for rate adaptation in variable bitrate channels.
