flw-net's Issues

训练LOLv1数据集

请问一下作者,为什么我用LOL_v1的数据集训练出来的模型,在对v2的测试集做测试的时候,得到的PSNR的值会比测v1的高出三个多点呢,请问训练v1数据集的时候,数据集是怎么划分的呢

无法在服务器上正常训练lOL_V2数据集

我今天测试了一下,发现在模型函数中,enhance_image = F.softplus(self.e_conv7(x6)),在经过softplus()之前,self.e_conv7(x6)的输出图像是有图像信息的,不是纯色,但是经过softplus()之后,enhance_image 就变成了之前的那个样子,基本上为纯色,没有任何信息,导致网络训练不起来。但是这种问题在我自己的电脑上就没有

过亮/白色区域增强图片出问题

大佬,我用你的代码跑LOLV1 和LOLV2,但是跑出来的结果都有些问题,我发现是在亮度过高的区域,增强过后的图片会变成这样:
low00769

我的猜测是白色太亮了,和原本的颜色加在一起会变成奇奇怪怪的颜色,最后超出了白色,变成了0,就是黑色,但是我不太清楚这要怎么解决,请问大佬遇到过这样的问题吗,感谢!

NIQE codes

I found some methods online for calculating the NIQE metric, and I used them to test the enhancement results, but the results I got were inconsistent with the ones provided in your paper. If possible, could you please share the code you used to calculate the NIQE?

about code

Dear author
I would appreciate it if you could publish the entire code and write a note about the code needing a torch version, etc

训练psnr

请问一下作者,为什么我用您给的代码给LOL_v2数据集训练时,PSNR和SSIM的值会从一开始就越来越低直到为负值呢

损失函数调整

关于上一个issue里面,使模型应对过饱和/过曝光的调整,请问张老师有打算把更改过的损失函数更新嘛?或者张老师有打算出一篇新论文,在里面启用新的损失函数吗?我尝试删除SSIM和L1进行训练,仍旧是越来越亮。感谢!

图片路径

filePath = 'F:/FlW-Net/low'
filePath_high = 'F:/FlW-Net/high'
想请教一下,是只修改这个路径成自己的就可以运行了吗,Traceback (most recent call last):
File "F:\FLW-Net\lowlight_test.py", line 132, in
runtime,Loss_psnr,Loss_ssim = lowlight(image_name,image_high_name,expect_mean[i])
File "F:\FLW-Net\lowlight_test.py", line 31, in lowlight
data_lowlight = Image.open(image_path)
File "F:\ANACONDA3\envs\yolov7\lib\site-packages\PIL\Image.py", line 3218, in open
fp = builtins.open(filename, "rb")
FileNotFoundError: [Errno 2] No such file or directory: 'F:/FlW-Net/low337.png',,,为什么运行test.py会报错呢?

Bug?Line 250 in Myloss.py

Hi, I found that there is something error in the code. Is that gradient_orig_abs instead of gradient_orig1_abs?
