Efficient Real-Time 4K Super-Resolution of Compressed AVIF Images: Insights from the AIS 2024 Challenge

The AIS 2024 Real-Time Image Super-Resolution (RTSR) Challenge introduced a novel benchmark for upscaling compressed 540p AVIF images to 4K resolution in real-time on commercial GPUs. The challenge attracted 160 participants, with 25 teams submitting their code and models. The solutions present novel designs tailored for memory-efficiency and runtime on edge devices, achieving significant PSNR improvements over Lanczos interpolation while processing images under 10ms.
