为何感觉效果较差

I am interested in the article, and I think it's a good job. I want to know whether you retain the NIQE model, my test data are bigger than article?

Hello, I have two questions about your loss functions. In your paper, the Illumination-guided noise estimation loss is shown as: ![image-20210525150617818](https://user-images.githubusercontent.com/55617704/119455470-36e49600-bd6c-11eb-868d-771270e692bf.png) But in your codes, wn(x) represents illumination and wr(x)...

> def noise_loss(image, illumination, reflectance, noise): weight_illu = illumination weight_illu.detach() loss = weight_illu*noise return torch.norm(loss, 2)

Although the enhanced results is somehow underexposed, it's good enough. However, more work may need to be done upon speed.
