The picture without the curve is your "baseline". The "mask" file is as separate image consisting only of white and black spaces, the white space being what you want to compare, the black being what you want to have ignored.
You're going to want to use the "Mask" feature of image comparison. You're going to have a baseline object with a blank screen. You're going to apply the mask. If the result of the Compare method returns "false", then you have a curve in the region. If it returns true, then the regions match meaning it's blank.

So can I add an edited picture with no curve to my project, and build the mask off that?

OK. I'll go search the help files and raise a ticket with support if necessary after I've played around with this. Thanks all.
