This paper reviews the third biennial challenge on spectral reconstruction from RGB images,
ie, the recovery of whole-scene hyperspectral (HS) information from a 3-channel RGB …

This paper reviews the NTIRE 2023 challenge on image denoising (sigma= 50) with a focus
on the proposed solutions and results. The aim is to obtain a network design capable to …

Deep learning based approaches has achieved great performance in single image super-
resolution (SISR). However, recent advances in efficient super-resolution focus on reducing …

Recent advances in single image super-resolution (SISR) have achieved extraordinary
performance, but the computational cost is too heavy to apply in edge devices. To alleviate …

This report introduces two high-quality datasets Flickr360 and ODV360 for omnidirectional
image and video super-resolution, respectively, and reports the NTIRE 2023 challenge on …

In this report, we summarize the first NTIRE challenge on light field (LF) image super-
resolution (SR), which aims at super-resolving LF images under the standard bicubic …

This paper reviews the NTIRE 2023 challenge on image super-resolution (x4), focusing on
the proposed solutions and results. The task of image super-resolution (SR) is to generate a …

Recently, a number of CNN based methods have made great progress in single image
super-resolution. However, these existing architectures commonly build massive number of …

This paper introduces a novel benchmark for efficient upscaling as part of the NTIRE 2023
Real-Time Image Super-Resolution (RTSR) Challenge, which aimed to upscale images …

Over the past few years, high-definition videos and images in 720p (HD), 1080p (FHD), and
4K (UHD) resolution have become standard. While higher resolutions offer improved visual …
