hi sorry to bother you i meet the problem ,can yo help me?

hello
For the crop attack, I trained the model by setting the parameter(0.0225) according to the paper and test (0.035). But the effect was not as good as the result in the paper, it was even worse. Could u tell me the reason? thx

Hello, thanks for the code, but I'm having a problem.
For a photo that has been watermarked with your model, I save the watermark in advance, and then put the image into the decoder to extract, I tested a hundred photos, but the error rate of each is 0.4~0.5,and I also set only_decoder=True,is it a problem with my code?
Thanks for your code.
The message length of the diffusion model is 30 bits, and 256 bits when fully connected. When I change the length to another value for testing, I get an error. If I want to increase the message length, e.g. to 128 or 256 bits, what should I do, do I need to retrain.
Can this use a two-stage training strategy?
Hi, I am wondering to know how you chose the training data and val data from Imagenet?
Hello,Do datasets take long to load when you train models? What is the general training time?
I use the COCO2014 as the training datasets,it takes a long time to load.
save_images(saved_all, epoch, result_folder + "images/", resize_to=(W, H)) in train.py may occur error! since the param "saved_all" can be NONE !
你好,读了你的论文,受益匪浅,非常感谢!
我用你本仓库的代码训练模型时遇到一些疑惑,想咨询一下作者
(2) 为保证模型泛化和迁移性,作者在图像输入网络前做了数据增强,to_tensor()归一化后,采用Normalize([0.5, 0.5, 0.5], [0.5, 0.5, 0.5])进行正则化,此处我修改为Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225],不知为何,用后者Normalize,生成的水印图像除了包含不规则的改动,还会包含规则的网格状的亮点(如下图),而前者Normalize只有一些不规则的改动。想问作者是否遇到这个问题。
(3) 代码中计算PSNR和SSIM,是在模型输出的图像和数据增强后的图像之间计算的,这样说不上错,但是个人认为直接计算 原始图像和水印图像的PSNR和SSIM更好,毕竟模型输出的图张量 还需要 reverse normalize 才能转换为 水印图像。
感谢!:)
作者你好,请问下论文结尾处message经过diffusion和没有经过diffusion的两张图片是如何获得的?
There might be an error in train.py:
"TypeError: ssim() got an unexpected keyword argument 'reduction', (line 98, in train.py), ssim = 1 - 2 * kornia.losses.ssim(encoded_images.detach(), images, window_size=5, reduction="mean"). "
It seems that "ssim" should be "ssim_loss". Is it right?
在BasicBlock中,第二个“nn.Conv2d(in_channels=out_channels, out_channels=out_channels // r, kernel_size=1, bias=False)”里面in_channels应该为out_channels // r, out_channels = out_channels,这个chennel数量好像有误
I hope this message finds you well. I am writing to seek your assistance with an issue we encountered while attempting to replicate your project [Project Name]. We appreciate the work you've done and were eager to explore it further.
However, during the replication process, we faced a runtime error that halted our progress. The error message we received was as follows:
project_name = MBRS
with_diffusion = False
only_decoder = False

, but unfortunately, we haven't been able to resolve the issue. We were wondering if you might have any insights or suggestions that could help us move forward.
sir,sorry to bother you ,if i want to know the message the model embed,what should i do
Why is the value of mav_val
not 255 but 2.
psnr = kornia.losses.psnr_loss(encoded_images.detach(), images, 2)
Acctually, since the channel obtained using DataLoader is RGB, with a value range of 0-1, the calculation formula of PSNR should be
psnr = kornia.losses.psnr_loss(encoded_images.detach()*255, images*255, 255)
This error causes the calculation result of PSNR to be larger than the correct one.
