2、简单的引入CLIP问题:因为图像损坏给特征对齐带来了困难,导致视觉语言模型无法有效地捕获退化图像和语义之间的细粒度差距,所以简单地引入视觉语言信息并不能获得显著的性能 二、Contribution 1、网络结构:CLIP-Fourier Guided Wavelet Diffusion (CFWD). 将多模态引入到扩散模型中用于低光图像增强 2、多模态监督:首次将...
In our method, the low-light image is firstly transformed into the amplitude component and phase component via Fourier transform. The luminance of low-light image is enhanced by CycleGAN in the amplitude domain, and the phase component is denoising. The cycle consistency losses both in ...
Embedding Fourier for Ultra-High-Definition Low-Light Image...openreview.net/forum?id=5N0wtJZ89r9 1、论文速读 1.1 论文试图解决什么问题? 近年来,随着先进成像传感器和显示器的出现,超高清(UHD)成像技术得到了快速发展。虽然超高清成像提供了广泛的应用,并使图像质量有了显著的不同,但额外的像素也对现有...
This is the official pytorch implementation of "FourLLIE: Boosting Low-Light Image Enhancement by Fourier Frequency Information" (ACM MM 2023) - wangchx67/FourLLIE
Frequency information ( e.g ., Discrete Wavelet Transform and Fast Fourier Transform) has been widely applied to solve the issue of Low-Light Image Enhancement (LLIE). However, existing frequency-based models primarily operate in the simple wavelet or Fourier space of images, which lacks ...
假设输入的张量是x,那么这句代码的作用是将x在第1维(即行数)上分别切割为两个长度分别为self.split_len1和self.split_len2的子张量,分别赋值给变量x1和x2。 其中,narrow()函数的参数含义分别为: dim:表示对哪个维度进行切片,这里是第1维(即行数)。
The natural statistics of audiovisual speech highlight the temporal correspondence between visual and auditory prosody, with lip, jaw, cheek and head movements conveying information about the speech envelope. Low-frequency spatial and temporal modulations in the 2–7 Hz range are of particular ...

Therefore, compared with the original local region, the new matrix can better highlight the sparsity of the anomaly pixels, which makes the subsequent low-rank background information extraction more accurate. After the construction matrix is designed, the construction matrix is used to decompose the...
The causes of ventricular fibrillation (VF) are not yet elucidated, and it has been proposed that different mechanisms might exist. Moreover, conventional analysis methods do not seem to provide time or frequency domain features that allow for recognitio
