第四名NWPU-DiffLight(西工大)组合了很多种方法,提出了DiffLight(发表在了CVPR workshop2024),分成了两个分支,去噪增强分支用到了DiffIR的后向过程(扩散模型)和LEDNet,细节保留分支用到了Restormer和PPF。 第五名GiantPandaCV(华南理工大学)使用了Mamba,并提出了一种叫做UHDMamba的新模型。 另外,值得注意的是,Cid...
2024CVPR_Low-light Image Enhancement via CLIP-Fourier Guided Wavelet Diffusion(CFWD) 一、Motivation 1、单模态监督问题:大多数方法往往只考虑从图像层面监督增强过程,而忽略了图像的详细重建和多模态语义对特征空间的指导作用。这种单模态监督导致不确定区域的次优重建和较差的局部结构,导致视觉结果不理想的出现。--...

Diffusion models have achieved promising results in image restoration tasks, yet suffer from time-consuming, excessive computational resource consumption, and unstable restoration. To address these issues, we propose a robust and efficient Diffusion-based Low-Light image enhancement approach, dubbed DiffLL...

2023 Elsevier Inc.In the case of insufficient illumination conditions, the quality of the captured image is poor. At this time, increasing the brightness of the dark region of the whole image will inevitably aggravate noise pollution. Therefore, the ideal state of low-light image enhancement shoul...
A = imread("lowlight_1.jpg"); imshow(A) title("Original Image") Localized Brightening Brighten the low-light image in proportion to the darkness of the local region, then display the brightened image. Dark regions brighten significantly. Bright regions also have a small increase in brightness...
Low-light images suffer from poor visibility and noise. In this paper, a low-light image enhancement method based on Retinex decomposition is proposed. A pyramid network is first utilized to extract ...
