For a real-world blurred image #15

Closed robbiewongBD closed 5 years ago

How could I obtain the noise level(Isigma) of a real-world blurred image where the PSF is also unknown? Is there any algorithm recommended to do that?

For blur kernel, you may refer to https://github.com/cszn/IRCNN/issues/5 For noise level, you can use a grid search to find the best noise level.
