Sape: Spatially-adaptive progressive encoding for neural optimization

A Hertz, O Perel, R Giryes… - Advances in …, 2021 - proceedings.neurips.cc
Multilayer-perceptrons (MLP) are known to struggle learning functions of high-frequencies,
and in particular, instances of wide frequency bands. We present a progressive mapping …

Smooth shells: Multi-scale shape registration with functional maps

M Eisenberger, Z Lahner… - Proceedings of the IEEE …, 2020 - openaccess.thecvf.com
We propose a novel 3D shape correspondence method based on the iterative alignment of
so-called smooth shells. Smooth shells define a series of coarse-to-fine shape …

Sigma: Scale-invariant global sparse shape matching

We propose a novel mixed-integer programming (MIP) formulation for generating precise
sparse correspondences for highly non-rigid shapes. To this end, we introduce a projected …

[HTML][HTML] SHREC'20: Shape correspondence with non-isometric deformations

RM Dyke, YK Lai, PL Rosin, S Zappalà, S Dykes… - Computers & …, 2020 - Elsevier
Estimating correspondence between two shapes continues to be a challenging problem in
geometry processing. Most current methods assume deformation to be near-isometric …

Shape Non-rigid Kinematics (SNK): A Zero-Shot Method for Non-Rigid Shape Matching via Unsupervised Functional Map Regularized Reconstruction

S Attaiki, M Ovsjanikov - Advances in Neural Information …, 2024 - proceedings.neurips.cc

Surface maps via adaptive triangulations

P Schmidt, D Pieper, L Kobbelt - Computer Graphics Forum, 2023 - Wiley Online Library
We present a new method to compute continuous and bijective maps (surface
homeomorphisms) between two or more genus‐0 triangle meshes. In contrast to previous …
