Noise on output

[AIisCool]

Usually on darker areas, there is some noise like this:

Is there a way to reduce that noise? Or add something to the code to denoise it? Thank you🙏

PASD always tends to generate details. I am working on it to reduce the artifacts.

@yangxy Ok, thank you for your continued work on this! Very amazing!

Can zero terminal SNR solve this issue?

Thanks for your advice. I have tried the offset noise trick (similar to the zero terminal SNR) and it seems it can partly solved the issue. The code is updated. Please have a try now.

Hi, there. I have solved this issue by initializing the latents with LR images. And the SR results also become much more stable. The source codes have been updated.

Hi, I have added a new parameter --added_noise_level to make up the missing details. Interestingly, it can be used to control the detail level. Please have a try.
