报告摘要：
With the rapid advances of 3D surface scanning technologies and medical modalities for volumetric objects, high-fidelity surface models and volumetric datasets of tremendous size have been routinely acquired through the state-of-the-art hardware systems. This talk focuses on the challenging research problem of how to compute the best possible data registration between different objects of arbitrarily complicated topological types and how to further broaden conventional application scopes in visual computing beyond the traditional boundary of computer aided geometric computing and interactive 3D graphics. One of our recent research activities aims to seek accurate and efficient solutions to this fundamental and significant problem. In particular, we have articulated a general and powerful data modeling and analysis paradigm based on shape registration for objects in different dimensions with arbitrary topologies: in the curve case, we devise the conformal invariants as curve signatures; in the surface case, we exploit techniques of topological decomposition and quasi-conformal mapping; and in the volumetric case, we focus on harmonic mapping based on Green function theory. The great potential of our shape registration framework will be highlighted through many valuable applications such as shape analysis, deformation editing, animation morphing, information transfer and reuse, finite element meshing, texture transplant, and physics-based modeling and simulation. We envision much broader application scopes in many visual computing fields including computational vision, shape data base, and content-driven information retrieval, digital medicine, material synthesis, virtual environments, etc.
