Ricci flow for 3D shape analysis

W Zeng, D Samaras, D Gu - IEEE Transactions on Pattern …, 2010 - ieeexplore.ieee.org
Ricci flow is a powerful curvature flow method, which is invariant to rigid motion, scaling,
isometric, and conformal deformations. We present the first application of surface Ricci flow …
