《An Experiment-Based Review of Low-Light Image Enhancement Methods》 在弱光照条件下拍摄的图像往往具有亮度低、对比度低、灰度范围窄、颜色失真等特点,并且噪声较大,严重影响了人眼的主观视觉效果,极大地限制了各种机器视觉系统的性能。 微光图像增强的作用是提高这些图像的视觉效果,以利于后续处理。本文综述了近几...
因此,我们用元素加法代替UNet中跳过连接阶段使用的通道连接。 该网络的主要思想是通过照度和噪声的联合分布映射,将弱光图像转换为正光图像。因此,我们将DE分支获得的光照和噪声的联合分布作为样式编码嵌入到低光图像中。为了更好地融合光照和噪声风格代码中的信息,本文提出了一种分布融合策略DFS,用于生成器网络中的多尺...
【AAAI2023】Ultra-High-Definition Low-Light Image Enhancement: A Benchmark and Transformer-Based Method 这个论文首先构建了ultra-high definition low-light (UHD-LOL)数据集,然后提出了 Low-Light Transformer (LLFormer)。 LLFormer 的整体框架如下所示,可以看出和 Restormer 有些类似。我的理解,作者改进了三...
本文介绍的是一种比较实用的低照度图像增强效果很好的方法,Xuan Dong论文《Fast efficient algorithm for enhancement of low lighting video》 概述 低光照图像取反(255 - 低光照图像),和有雾图像存在一些共性,比如在天空或者遥远的背景这些地方,亮度值都是很高的,但在近景的 RGB 三通道中至少有一个亮度值很低。
Images captured in low-light conditions usually suffer from very low contrast, which increases the difficulty of subsequent computer vision tasks in a great extent. In this paper, a low-light image enhancement model based on convolutional neural network and Retinex theory is proposed. Firstly, we ...

In the process of low-light image enhancement, how to handle the noise effectively is an important yet challenging problem. Based on Retinex decomposition theory, this paper proposes a deep learning method for low-light image enhancement with joint decomposition and denoising. First, we propose a ...
This paper presents a low-light image enhancement method using the variational-optimization-based Retinex algorithm. The proposed enhancement method first estimates the initial illumination and uses its gamma corrected version to constrain the illumination component. Next, the variational-based minimization ...
