Procrustes transformation information


A Procrustes transformation is a geometric transformation that involves only translation, rotation, uniform scaling, or a combination of these transformations. Hence, it may change the size, position, and orientation of a geometric object, but not its shape.

The Procrustes transformation is named after the mythical Greek robber Procrustes who made his victims fit his bed either by stretching their limbs or cutting them off.
