原始的图像是正常光照下的,论文这里是采用matlab中的-imadjust将图像进行伽马非线性调暗。 进行伽马调暗的公式如下: 当γ小于1时,图片变亮; 当γ等于1时,图片不变; 当γ大于1时,图片变暗。 为了模拟自然拍摄情况下低质量的图片,图像数据进行了添加高斯噪音的处理。这里使用MATLAB中的imnoise实现。 高斯噪音处理公...
When an image is captured in low-light, it gets the low visibility. To overcome the low visibility of the image, some operations are to be performed. But in this paper, image enhancement is introduced using illumination mapping. First, R, G, B maximum values in each pixel of the ...
MATLAB implementation of the algorithm in the paper "Low-Light Image Enhancement with Semi-Decoupled Decomposition". IEEE TRANSACTIONS ON MULTIMEDIA.1 IntroductionLow-light image enhancement is important for highquality image display and other visual applications. It is a non-trivial task, as the enha...
Implementation of the paper, "LIME: Low-Light Image Enhancement via Illumination Map Estimation" - estija/LIME
The poor visibility of low-light images makes them unsuitable for computer vision algorithms and human observation. Many image-enhancing methods have been suggested as techniques for this problem. But it does not restore colors and improve lighting properly. Therefore, in this study, we propose an...
This manuscript introduces an innovative multi-stage image fusion framework that adeptly integrates infrared (IR) and visible (VIS) spectrum images to surmount the difficulties posed by low-light settings. The approach commences with an initial preproces
Self-supervised Image Enhancement Network: Training with Low Light Images Only 现有的图像增强数据集都是通过合成或者调整曝光时间得到的,但存在两个问题:①如何确保预先训练的网络可以用于不同设备、不同场景和不同照明条件下收集的图像,而不是构建新的训练数据集。②如何确定用于监督的正常光图像是最好的,因为相...
Nighttime low illumination image enhancement is highly desired for outdoor computer vision applications. However, few works have been studied towards this goal. In addition, the low illumination enhancement problem becomes very challenging when the depth
