Having dabbled with image processing, your comment reminded me of the Fourier Mellin transform, which can be used for translation, rotation and scale invariant feature detection. I did a quick search and came up with this paper[1], and while they don't use the Fourier-Mellin transform, they do use a log-polar transform[2], where rotation and scaling are transformed to translations. This, they claim, result in much improved classification of rotated and scaled data. I haven't been keeping up on the latest in the ML field tho, so maybe it's rubbish, but like you I'd be surprised if some extra…
