摘要:

视频超分辨率(VSR)和帧内插(FI)是传统的计算机视觉问题,近年来随着深度学习的引入,其性能得到了提高。在本文中,我们调查的问题,联合上采样视频在空间和时间,这是越来越重要的显示系统的进步。一种解决方案是独立地逐个运行VSR和FI。这是非常低效的,因为每个解决方案中都涉及大量的深度神经网络(DNN)。为此,我们提出了一个端到端的DNN框架的空时视频上采样有效地合并VSR和FI到一个联合框架。在我们的框架中,提出了一种新的加权方案,有效地融合输入帧,而无需显式的运动补偿,有效地处理视频。结果显示,与基线相比,定量和定性结果都更好,同时减少了计算时间(快7倍)和参数数量(30%)。

英文摘要:

Video super-resolution (VSR) and frame interpolation (FI) are traditional computer vision problems, and the performance have been improving by incorporating deep learning recently. In this paper, we investigate the problem of jointly upsampling videos both in space and time, which is becoming more important with advances in display systems. One solution for this is to run VSR and FI, one by one, independently. This is highly inefficient as heavy deep neural networks (DNN) are involved in each solution. To this end, we propose an end-to-end DNN framework for the space-time video upsampling by efficiently merging VSR and FI into a joint framework. In our framework, a novel weighting scheme is proposed to fuse input frames effectively without explicit motion compensation for efficient processing of videos. The results show better results both quantitatively and qualitatively, while reducing the computation time (x7 faster) and the number of parameters (30%) compared to baselines.
