TL; DR: There are 24 ambiguities of the PCA-based canonical poses of point clouds! Correctly identifying them leads to much better performances in deep rotation-invariant point cloud analysis.

TL; DR: Geometric and probabilistic point cloud registration algorithms are developed independently so far. We propose a framework that unifies them together for an information-geometric perspective.
