{{main|Statistical shape analysis}}
The above-mentioned mathematical definitions of rigid and non-rigid shape have arisen in the field of [[statistical shape analysis]]. In particular, [[Procrustes analysis]] is a technique used for comparing shapes of similar objects (e.g. bones of different animals), or measuring the deformation of a deformable object. Other methods are designed to work with non-rigid (bendable) objects, e.g. for posture independent shape retrieval (see for example [[Spectral shape analysis]]).
