Getting Rid of Pixel Noise

I have an image with shading and I think I can get rid of it with some type of noise reduction, but not sure how to approach it. I think it'll increase the readability of my OCR image if I can.

try the Magick.NET equivalent of the following command line:

Code: Select all

convert 2V26YCCs0OmX.png -morphology close diamond:1 result.png
Please, always best to provide your IM version and platform when asking questions, since syntax may differ.
