Abstract
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.

本文作为AIS 2024实时图像超分辨率（RTSR）挑战的一部分，旨在在商业GPU上实时将压缩图像从540p升级到4K分辨率（4x倍）。为此，我们使用包含各种4K图像的多样化测试集。这些图像使用现代AVIF编码器压缩，而不是JPEG。所有提出的方法都超过了Lanczos插值在PSNR方面的保真度，并能在10ms内处理图像。在160名参与者中，有25支团队提交了其代码和模型。本调查描述了用于实时压缩高分辨率图像的最佳解决方案。
