[Insight-users] Level of noise in an image

[lena russo]

Hi Christopher,

thanks for your answer! I'm not very familiar with noise in images, but if I understand correctly the Wiener deconvolution filter requires knowledge about the nature of the noise itself. Am I correct? What if I don't know its nature but I need to find which kind of noise affected the image?

Many many thanks

Lena

Are you looking for the power spectral densities of the signal and noise?  You might consider the implementation of the Wiener deconvolution filter [1].

Hi all,

I'm trying to develop a good method to evaluate the level
 of noise in an image in order to filter the image accordingly and 
remove this noise. Have you got any suggestion?

Many many thanks for your help,
