Deformation-Guided Unsupervised Non-Rigid Shape Matching

no code implementations27 Nov 2023 Aymen Merrouche, Joao Regateiro, Stefanie Wuhrer, Edmond Boyer

Our approach is designed to be particularly robust when matching shapes digitized using 3D scanners that contain fine geometric detail and suffer from different types of noise including topological noise caused by the coalescence of spatially close surface regions.
