noise calculation software??

hi...
i've wrote a program to remove noise in an image. So, now i'm doing the testing. i want to calculate the amount of noise removed from the image. I've tried to look for a software to do this, but i didn't find any. is there anyone who knows any software or freeware that i can use to calculate the noise?

thanks...
