A Riemannian Approach for Spatiotemporal Analysis and Generation of 4D Tree-shaped Structures

"We propose the first comprehensive approach for modeling and analyzing the spatiotemporal shape variability in tree-like 4D objects, 3D objects whose shapes bend, stretch and change in their branching structure over time as they deform, grow, and interact with their environment. Our key contributio…
