标题： ICME 2025 Generalizable HDR and SDR Video Quality Measurement Grand Challenge

摘要： 本文报告了IEEE多媒体与展览国际会议（ICME）2025年关于可推广的HDR和SDR视频质量评估的大挑战。随着视频技术的快速发展，特别是高动态范围（HDR）和标准动态范围（SDR）内容的出现，对稳健且可推广的视频质量评估（VQA）方法的需求变得越来越迫切。现有的VQA模型通常难以在不同的动态范围、失真类型和多样的内容上保持一致的性能。该挑战旨在基准测试并促进能够联合处理HDR和SDR内容的VQA方法。在最终评估阶段，五支团队向全参考（FR）和无参考（NR）赛道提交了七种模型及技术报告。其中，四种方法超过了VMAF基线，而表现最佳的模型达到了最先进水平，为可推广的视频质量评估设定了新基准。 显示英文摘要

摘要： This paper reports IEEE International Conference on Multimedia \& Expo (ICME) 2025 Grand Challenge on Generalizable HDR and SDR Video Quality Measurement. With the rapid development of video technology, especially High Dynamic Range (HDR) and Standard Dynamic Range (SDR) contents, the need for robust and generalizable Video Quality Assessment (VQA) methods has become increasingly demanded. Existing VQA models often struggle to deliver consistent performance across varying dynamic ranges, distortion types, and diverse content. This challenge was established to benchmark and promote VQA approaches capable of jointly handling HDR and SDR content. In the final evaluation phase, five teams submitted seven models along with technical reports to the Full Reference (FR) and No Reference (NR) tracks. Among them, four methods outperformed VMAF baseline, while the top-performing model achieved state-of-the-art performance, setting a new benchmark for generalizable video quality assessment.
