This paper introduces a novel benchmark as part of the AIS 2024 Real-Time Image Super-Resolution (RTSR) Challenge, which aims to upscale compressed images from 540p to 4K resolution (4x factor) in real-time on commercial GPUs. For this, we use a diverse test set containing a variety of 4K images ranging from digital art to gaming and photography. The images are compressed using the modern AVIF codec, instead of JPEG. All the proposed methods improve PSNR fidelity over Lanczos interpolation, and process images under 10ms. Out of the 160 participants, 25 teams submitted their code and models. The solutions present novel designs tailored for memory-efficiency and runtime on edge devices. This survey describes the best solutions for real-time SR of compressed high-resolution images.

本论文介绍了AIS 2024实时图像超分辨率（RTSR）挑战的新型基准，旨在在商用GPU上实时将540p的压缩图像提升到4K分辨率（4倍因子）。使用包含各种从数字艺术到游戏和摄影的4K图像的多样化测试集。所有提出的方法相对于Lanczos插值都提高了PSNR保真度，并在10毫秒内处理图像。 在160个参赛者中，有25个团队提交了他们的代码和模型。这些解决方案设计出了适用于边缘设备的内存效率和运行时的新颖设计。本调查描述了对压缩高分辨率图像进行实时SR的最佳解决方案。
