Signature

def _cross_decomposition ( footprint , dtype = <class 'numpy.uint8'> )

Summary

Decompose a symmetric convex footprint into cross-shaped elements.

Extended Summary

This is a decomposition of the footprint into a sequence of (possibly asymmetric) cross-shaped elements. This technique was proposed in ^[1] and corresponds roughly to algorithm 1 of that publication (some details had to be modified to get reliable operation).
