What noise? What is it you want to remove? It has no noise, just various colors. Perhaps you mean more contrast?

try variations of:

Code: Select all

convert yCA1E.png -brightness-contrast 20,20 result.png

change the 20,20 as desired. See http://www.imagemagick.org/script/comma ... s-contrast

this internal point inside four number look like noise
