Hi All:
I'm trying to extract noise parameters from a gray image which contains an object. I did the binarisation then masked the image. I did this because I have the noise just around the object, so I want to ask how can I get the parameters of the noise from the masked image 'around the object'???
Thank you in advance

Maybe it has no noise. What do you consider to be noise? Do you have a noiseless "ground truth" image?

I'm not an electron microscope operator so I don't know. Maybe you can use a very long exposure to get the "no noise" case while a very short exposure will result in a noisy image.
