Abstract

Video super-resolution (SR) has important real world applications such as enhancing viewing experiences of legacy low-resolution videos on high resolution display devices. However, there are no visual quality assessment (VQA) models specifically designed for evaluating SR videos while such models are crucially important both for advancing video SR algorithms and for viewing quality assurance. This paper addresses this gap. We start by contributing the first video super-resolution quality assessment database (VSR-QAD) which contains 2,260 SR videos annotated with mean opinion score (MOS) labels collected through an approximately 400 man-hours psychovisual experiment by a total of 190 subjects. We then build on the new VSR-QAD and develop the first VQA model specifically designed for evaluating SR videos. The model features a two-stream convolutional neural network architecture and a two-stage training algorithm designed for extracting spatial and temporal features characterizing the quality of SR videos. We present experimental results and data analysis to demonstrate the high data quality of VSR-QAD and the effectiveness of the new VQA model for measuring the visual quality of SR videos. The new database and the code of the proposed model will be available online at https://github.com/key1cdc/VSRQAD .

超分辨率视频视觉质量评估数据库和模型

视频超分辨率（SR）在现实世界中有着重要的应用，例如在高分辨率显示设备上增强传统低分辨率视频的观看体验。然而，目前还没有专门用于评估 SR 视频的视觉质量评估 (VQA) 模型，而这类模型对于推进视频 SR 算法和保证观看质量都至关重要。本文正是为了弥补这一空白。首先，我们提供了第一个视频超分辨率质量评估数据库（VSR-QAD），该数据库包含 2,260 个 SR 视频，这些视频标注了平均意见分（MOS）标签，这些标签是由 190 名受试者通过约 400 个工时的心理视觉实验收集的。然后，我们以新的 VSR-QAD 为基础，开发了首个专门用于评估 SR 视频的 VQA 模型。该模型采用双流卷积神经网络架构和两阶段训练算法，旨在提取表征 SR 视频质量的空间和时间特征。我们展示了实验结果和数据分析，以证明 VSR-QAD 的高数据质量和新 VQA 模型在测量 SR 视频视觉质量方面的有效性。新数据库和拟议模型的代码将在 https://github.com/key1cdc/VSRQAD 上在线提供。

期刊介绍： The Society’s Field of Interest is “Devices, equipment, techniques and systems related to broadcast technology, including the production, distribution, transmission, and propagation aspects.” In addition to this formal FOI statement, which is used to provide guidance to the Publications Committee in the selection of content, the AdCom has further resolved that “broadcast systems includes all aspects of transmission, propagation, and reception.”
