Example of shape correspondence and Procrustes alignment. a Two randomly chosen foot meshes. Initially, the vertices (e.g. blue and red points) on these meshes do not correspond; b Foot meshes after shape correspondence. Their vertices (e.g. blue and red points) are matched and located on the same anatomical position; c Foot meshes after Procrustes alignment. The geometric distance between corresponding vertices (e.g. blue and red points) is minimized
