i find here on internet.it said opencv coin recognition will be available here.

The new generation of OpenCV bindings for Python are getting better and better with the hard work of the community. The new bindings, called “cv2” are the replacement of the old “cv” bindings; in this new generation of bindings, almost all operations returns now native Python objects or Numpy objects, which is pretty nice since it simplified a lot and also improved performance on some areas due to the fact that you can now also use the optimized operations from Numpy and also enabled the integration with other frameworks like the scikit-image which also uses Numpy arrays for image representation.
