Dynamic Neural Surfaces for Elastic 4D Shape Representation and Analysis

Awais Nizamani, Hamid Laga, Guanjin Wang, Farid Boussaid, Mohammed Bennamoun, Anuj Srivastava

CVPR 2025poster

We propose a novel framework for the statistical analysis of genus-zero 4D surfaces, i.e., 3D surfaces that deform and evolve overtime. This problem is particularly challenging due to the arbitrary parameterizations of these surfaces and their varying deformation speeds, necessitating effective spat…

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

Tahmina Khanam, Mohammed Bennamoun, Guan Wang, Guanjin Wang, Ferdous Sohel, Farid Boussaid +2

ECCV 2024oral

"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…
