Point-Based Shape Representation Generation with a Correspondence-Preserving Diffusion Model
Shen Zhu, Yinzhu Jin, Ifrah Zawar +1
We propose a diffusion model designed to generate point-based shape representations with correspondences. Traditional statistical shape models have considered point correspondences…

Quantifying Hippocampal Shape Asymmetry in Alzheimer's Disease Using Optimal Shape Correspondences
Shen Zhu, Ifrah Zawar, Jaideep Kapur +1
Hippocampal atrophy in Alzheimer's disease (AD) is asymmetric and spatially inhomogeneous. While extensive work has been done on volume and shape analysis of atrophy of the hippoca…
