The problem is image collections and finding the better of near duplicate images. There are many programs, free and costly, CLI or GUI oriented for finding visually similar images but I'm looking for a next step in the process. It's known that saving the same source image in JPEG format at different quality levels produces different images. The one at the lower quality having more JPEG artifacts.
I've been trying to find a method to compare two visually similar JPEG images and select the one with the fewest JPEG artifacts (or the one with the most JPEG artifacts, either will serve.)
I also suspect that this is going to be one of those "Well, of course, how else would you do it? It's so simple." moments.
Thanks in advance for reading, thinking and maybe responding to this."

Bigger File Size = Better Quality (Score:2)
Because of the way that JPEG compresses images, file size is directly proportionate to quality. Therefore, bigger file size = better quality.
