Shape from silhouettes based on a centripetal pentahedron model

Xin Liu, Hongxun Yao, Xilin Chen, Wen Gao
2008 Graphical Models  
In this paper we present a novel volumetric shape from silhouette (SfS) algorithm based on a centripetal pentahedron model (pent-model).  ...  The pent-model is an object-centered volumetric model composed of a set of pentahedrons cut from the centripetal triangular pyramids, which together partition the 3D space.  ...  Aiming at reconstructing precise visual hulls from silhouettes robustly and efficiently, we propose a novel volumetric SfS algorithm based on a centripetal pentahedron model (pent-model).  ...
