摘要
本文回顾了 NTIRE 2022 压缩视频超分辨率与质量增强挑战赛。在该挑战赛中，我们提出了 LDV 2.0 数据集，其包含 LDV 数据集（240 个视频）以及额外 95 个视频。本挑战赛包含三个赛道。赛道 1 旨在增强由 HEVC 在固定 QP 下压缩的视频。赛道 2 和赛道 3 同时针对 HEVC 压缩视频的超分辨率与质量增强，分别要求 x2 和 x4 超分辨率。三个赛道共吸引了超过 600 次注册。在测试阶段，分别有 8 支、8 支和 12 支队伍向赛道 1、2、3 提交了最终结果。所提出的方法与解决方案衡量了压缩视频超分辨率与质量增强的当前最优（SOTA）水平。所提出的 LDV 2.0 数据集可在 https://github.com/RenYang-home/LDV_dataset 获取。本挑战赛主页（含开源代码）位于 https://github.com/RenYang-home/NTIRE22_VEnh_SR。
