features from images. What I'd like is, given a contour as a serie of dots, how can I mask (to zero) the points outside the contour?

There happens to be an implementation of that both in scikit-image and in matplotlib. We use it only internally at the moment, so it is exposed as: from skimage._shared.geometry cimport point_in_polygon and (with a slightly more Pythonic interface) as skimage.morphology._pnpoly If you think it's useful on a more general level, a pull-request to expose it would be very welcome!
