But wouldn't it require you to find how the target image's particular watermark was warped? None of the other watermarks will have precisely the same warping parameters as that image's watermark. You could attempt to de-warp the watermark in place on the image, but that would seem to be likely to warp the image as well, no?

you could de-warp the watermark in place, and this would warp the image but you could reverse the warp after you're done removing the watermarks.
