NTIRE 2021 Challenge on Video Super-Resolution
This is an incremental challenge report for the computer vision community, focusing on benchmarking video super-resolution methods.
The paper reviews the NTIRE 2021 Challenge on Video Super-Resolution, tackling the problem of enhancing low-resolution videos to high-resolution, with results showing 14 teams competed in each of two tracks to achieve state-of-the-art performance.
Super-Resolution (SR) is a fundamental computer vision task that aims to obtain a high-resolution clean image from the given low-resolution counterpart. This paper reviews the NTIRE 2021 Challenge on Video Super-Resolution. We present evaluation results from two competition tracks as well as the proposed solutions. Track 1 aims to develop conventional video SR methods focusing on the restoration quality. Track 2 assumes a more challenging environment with lower frame rates, casting spatio-temporal SR problem. In each competition, 247 and 223 participants have registered, respectively. During the final testing phase, 14 teams competed in each track to achieve state-of-the-art performance on video SR tasks.
