您好！非常感谢您开源您的代码！ 我对test.py的第97行开始的测量PSNR和SSIM的代码有些疑惑： 第111行测量函数的输入是乘以了255的，为什么第97行要除以255.呢 以及第103行到第109行的裁剪操作的目的是什么呢 非常感谢您能够回答我的问题！

关于哈尔小波下采样

一般的哈尔小波变换是基于pytorch_wavelets库做的，本文设置一些haar_weight，通过卷积形式来实现，不太明白为什么这样可以，可以解释一下吗，谢谢

Firstly, many thanks for the authors' great job on image rescaling!I've trained the model in 'IRN 4x mode', and got a really good result with 'DIV2K' validation dataset.But when I...

I have used your code for replication, and the first tens of thousands of loss and validation results are as follows. Is this convergence normal？ (training on div2k, val in...

Thank you for your impressive work. But when I try to recurrent this network(I rewrite the code myself), sometimes the loss will suddenly increase by 10 times. The structure of...

我没有找到train_IRN_x2对应的gan训练的文件，请问是没有上传吗？ 另外这里train_IRN_x2_finetune.yml的作用是什么？论文中的2x 指标是用gan训练的结果吗？

Thanks for your amazing work. I tried to use the IRN model to restore the lost high-frequency information in the signal. The model training results show that the matching effect...

您好，请问一下，在训练IRN_x4的时候，得到的低分辨率小图很正常，但是重建后的大图为什么会出现彩色小点点，在调整完lambda_fit_forw到160，还是出现彩色小点？望解答啊 Hello, I'm training IRN_ In x4, the low resolution small image is normal, but why do the reconstructed large image appear small color dots? After adjusting the lambda_ fit_...
