Infimum Dimension Nash Embeddings for 2D Projective Shape Analysis
This work determines the minimum dimension isometric (distance-preserving or Nash) vector embedding for a projective space and determines an embedding for the Cartesian product of projective planes which is used to develop a novel extrinsic mean test as well as a novel homogeneity test for 2D projective shape analysis.
