Noise level on a single image

Dear community users,

I am trying to find the noise level on a single image. Is there any node for that?

Thank you,

Chakib, 

Hi ChakibO, 

could your provide a bit more information how you would compute the noise-level for your images in general?

Best,

Christian

I would like to have for exemple the mean absolute deviation from a rectangular selection on my image. Is that possible?

Thank you,

Chakib,

 

You can use the Interactive Annotater Node to draw a rectangular selection and then compute your features with the Image Segment Feature node.

 

Best,

Tim
