i don't think, this will work. hu moments are just 7 numbers, while you usually need a few thousand, to make a good feature there.

@berak I have found some papers but after a quick reading I'm not convinced

@LBerger, yes, that idea has been tried (~10years ago). but more successful with like zernike or chebychev moments (instead of Hu), and working on image patches.

what can i say, i tried some of those, too, and other methods just worked better. in the end, the DNN folks have won that race, for sure.

(best thing, opencv has to offer here, is the new BIF descriptor (gabor-filters, in opencv_contrib) with an ANN, imho.)
