NTIRE 2024 Challenge on Image Super-Resolution ($\times$4): Methods and Results
It benchmarks current trends in super-resolution for researchers and practitioners, but is incremental as it focuses on existing metrics and datasets.
This paper reviews the NTIRE 2024 challenge on 4x image super-resolution, where participants developed solutions to generate high-resolution images from low-resolution inputs, with the best methods achieving state-of-the-art performance as measured by PSNR on the DIV2K dataset, attracting 199 registrants and 20 valid submissions.
This paper reviews the NTIRE 2024 challenge on image super-resolution ($\times$4), highlighting the solutions proposed and the outcomes obtained. The challenge involves generating corresponding high-resolution (HR) images, magnified by a factor of four, from low-resolution (LR) inputs using prior information. The LR images originate from bicubic downsampling degradation. The aim of the challenge is to obtain designs/solutions with the most advanced SR performance, with no constraints on computational resources (e.g., model size and FLOPs) or training data. The track of this challenge assesses performance with the PSNR metric on the DIV2K testing dataset. The competition attracted 199 registrants, with 20 teams submitting valid entries. This collective endeavour not only pushes the boundaries of performance in single-image SR but also offers a comprehensive overview of current trends in this field.
