Centralised moments
The definition of a discrete centralised moment as described by Hu[6] is:
Two dimensional centralised moment

This is essentially a translated Cartesian moment, which means that the centralised moments are
invariant under translation.
To enable invariance to scale, normalised moments Two dimensional scale-normalised centralised moment are used [20], given by:
