There are other shape properties scale-rotation invariant except HuMoment? There are example that show me how can i implement them? I find this example in c++ http://stackoverflow.com/questions/8675878/opencvc-calculating-moments-from-contour but i prefer working in python
Which is the difference between WeightedNormalizedMoments, WeightedHuMoments and HuMoments? (http://scikit-image.org/docs/0.6/api/skimage.measure.html)
