New framework unifies landmark shape spaces with induced metrics

Researchers have developed a novel framework that unifies existing approaches to landmark shape spaces. This new construction integrates Kendall's landmark shape spaces, which factor out rigid motions and fix scale, with spaces that use Riemannian metrics derived from Sobolev metrics on the diffeomorphism group. The resulting spaces maintain desirable properties such as landmark regularity, ambient space metric definition, preservation of local rigid transformations, and removal of global rigid motions, while also fixing scale.
