HMC: Hierarchical Mesh Coarsening for Skeleton-free Motion Retargeting

Understand

We present a simple yet effective method for skeleton-free motion retargeting.

• Previous methods transfer motion between high-resolution meshes, failing to preserve the inherent local-part motions in the mesh.
• Addressing this issue, our proposed method learns the correspondence in a coarse-to-fine fashion by integrating the retargeting process with a mesh-coarsening pipeline.
• First, we propose a mesh-coarsening module that coarsens the mesh representations for better motion transfer.
