摘要
本文回顾了首届 NTIRE 压缩视频质量增强挑战赛，重点介绍所提出的方法与结果。本挑战赛采用了新的大规模多样视频（LDV）数据集。挑战赛包含三个赛道。赛道 1 与 2 旨在增强由 HEVC 在固定 QP 下压缩的视频，而赛道 3 设计用于增强由 x265 在固定码率下压缩的视频。此外，赛道 1 与 3 的质量增强目标为提升保真度（PSNR），赛道 2 目标为增强感知质量。三个赛道共吸引 482 次注册。在测试阶段，分别有 12 支、8 支与 11 支队伍提交了赛道 1、2 与 3 的最终结果。所提出的方法与方案衡量了视频质量增强的最先进水平。挑战赛主页：https://github.com/RenYang-home/NTIRE21_VEnh
