CARL: A Framework for Equivariant Image Registration

CVPR 2025poster

Image registration estimates spatial correspondences between image pairs. These estimates are typically obtained via numerical optimization or regression by a deep network. A desirable property is that a correspondence estimate (e.g., the true oracle correspondence) for an image pair is maintained u…

NePhi: Neural Deformation Fields for Approximately Diffeomorphic Medical Image Registration

ECCV 2024poster

"This work proposes NePhi, a generalizable neural deformation model which results in approximately diffeomorphic transformations. In contrast to the predominant voxel-based transformation fields used in learning-based registration approaches, NePhi represents deformations functionally, leading to gr…

Accurate Point Cloud Registration with Robust Optimal Transport

NeurIPS 2021poster

This work investigates the use of robust optimal transport (OT) for shape matching. Specifically, we show that recent OT solvers improve both optimization-based and deep learning methods for point cloud registration, boosting accuracy at an affordable computational cost. This manuscript starts with…
