central_moments — 3D moment_invariant op

• Data kinds: points → table

• Call: import moments3d; moments3d.central_moments(points, max_order: 'int' = 3) -> 'dict' (or ops3d.get("central_moments"))

Usage

The centroid-centred central moments μ_{pqr} (translation invariant; keys are (p,q,r)).

• Operator provenance and references — the sources of the research/methods this op family came from.
