摘要:

弱光图像增强是一项计算机视觉任务,它将暗图像增强到适当的亮度。它也可以被看作是一个不适定的问题,在图像恢复领域。随着深度神经网络的成功,卷积神经网络超越了传统的基于算法的方法,成为计算机视觉领域的主流。为了提高增强算法的性能,我们提出了一个图像增强网络(HWMNet)的基础上改进的层次模型:M-Net+。具体来说,我们在M-Net+上使用半小波注意力块来丰富小波域的特征。此外,我们的HWMNet在定量指标和视觉质量方面对两个图像增强数据集具有竞争力的性能结果。源代码和预训练模型可在https://github.com/FanChiMao/HWMNet上获得。

英文摘要:

Low-Light Image Enhancement is a computer vision task which intensifies the dark images to appropriate brightness. It can also be seen as an ill-posed problem in image restoration domain. With the success of deep neural networks, the convolutional neural networks surpass the traditional algorithm-based methods and become the mainstream in the computer vision area. To advance the performance of enhancement algorithms, we propose an image enhancement network (HWMNet) based on an improved hierarchical model: M-Net+. Specifically, we use a half wavelet attention block on M-Net+ to enrich the features from wavelet domain. Furthermore, our HWMNet has competitive performance results on two image enhancement datasets in terms of quantitative metrics and visual quality. The source code and pretrained model are available at https://github.com/FanChiMao/HWMNet.
