Resumo

The extraction and classification of multi-type (point, curve, patch) features on manifolds are extremely challenging due to the lack of rigorous definition for diverse feature forms. This paper seeks a novel solution of multi-type features in a mathematically rigorous way and proposes an efficient method for feature classification on manifolds. We tackle this challenge by exploring a quasiharmonic field (QHF) generated by elliptic PDEs, which is the stable state of heat diffusion governed by anisotropic diffusion tensor. Diffusion tensor locally encodes shape geometry, and controls velocity and direction of the diffusion process. The global QHF weaves points into smooth regions separated by ridges, and has superior performance in combating noise/holes. Our method’s originality is highlighted by the integration of locally-defined diffusion tensor and globally-defined elliptic PDEs in an anisotropic manner. At the computational front, the heat diffusion PDE becomes a linear system with Dirichlet condition at heat sources (called seeds). Our new algorithms afford automatic seed selection, enhanced by a fast update procedure in a high dimensional space. By employing diffusion probability, our method can handle both manufactured parts and organic objects. Various experiments demonstrate the flexibility and high performance of our method.
