摘要
本文介绍了 NTIRE 2026 图像超分辨率 (4) 挑战，这是 NTIRE 2026 工作坊的一个关联比赛，计划于 CVPR 2026 举行。该挑战旨在从通过 4 缩放因子进行 bicubic 下采样生成的低分辨率 (LR) 输入中重建高分辨率 (HR) 图像。目标是开发有效的超分辨率解决方案并分析该领域的最新进展。为反映图像超分辨率不断演变的目标，本次挑战包括两个轨道：(1) 恢复轨道，强调像素级保真度，根据 PSNR 对提交结果进行排序；(2) 感知轨道，关注视觉真实性，使用感知分数进行评估。本次挑战共有 194 名参赛者报名，31 支团队提交了有效条目。本报告总结了挑战设计、数据集、评估协议、主要结果以及参赛团队的方法。该挑战提供了一个统一的基准，为当前在图像超分辨率方面的进展及未来方向提供了洞见。
