Hi!

I'm trying to make a tool that can measure the quality of a fax file, comparing the received one with the one sent. I tried Phase_Correlation software, in order to see if the images are similar... but it's not enough. My purpose is to evaluate if the fax is legible after the transmission. Any ideas? Is there any way of comparing two tiffs? pdfs? or image files?

Thanks a lot
