Domain Crossover Non-Rigid Registration for 3D Human Meshes

Year: 2025

Type: conference-paper

Abstract: Non-rigid registration is essential for reconstructing dynamic and incomplete 3D human meshes, yet traditional methods often fail to achieve robust alignment in the sequence of high-motion deformations and missing geometry. We propose a domain crossover non-rigid registration (DCNRR) framework that addresses these challenges by effectively transferring informative features from 2D image space into the 3D mesh domain of three key stages: multi-view projection, hierarchical non-rigid registration, and topology-consistent completion. In the first stage, multi-view projections are used to extract 2D joint locations and deep features, which guide deformation in the 3D space. In the second stage, hierarchical joint priors and deep features collaboratively guide mesh alignment, enabling more accurate deformation in distal regions and complex poses. In the final stage, we apply a diffusion-based completion process in UV coordinates to reconstruct incomplete surface normals and refine missing mesh areas with topological consistency. Our approach achieves highly detailed and perceptually accurate mesh deformation. To validate our approach, we evaluate performance on a newly constructed dynamic human motion (DHM) dataset, as well as public datasets. Our method demonstrates state-of-the-art results in both geometric accuracy and stability, showing particular robustness in dynamic and incomplete mesh sequences.
