For several weeks, I've been taking advantage of MIT's Large-Scale Image Memorability - LaMem - to score different versions of the same image. The scores range from 0 to 1, where 1 is the most memorable. The difference between versions in most cases is relatively small, but telling. Because I generally agree with the scores, I like to use LaMem as sort of second opinion to choose a shot when a deadline doesn't allow looking away for a few days to gain perspective.
