In this paper, a technique for reconstructing the geometry of vasculatures using bivariate implicit splines is developed.  ...  With the proposed technique, an implicit geometry representation of the vascular tree can be accurately constructed based on the voxels extracted directly from the surface of a certain vascular structure  ...  RELATED WORK Surface reconstruction approaches for vasculatures can be grouped into two categories: skeleton-based surface reconstruction and skeleton-free surface reconstruction.  ...

We present a new method for the implicit reconstruction of branching shapes from a set of scattered data points. The method is based on the computation of a geometric skeleton inside the data set.  ...  This skeleton is simplified in order to filter noise and converted into skeletal elements -a graph of interconnected curves -that generate an implicit surface.  ...  Compared with previous approaches for reconstruction using implicit surfaces, the introduction of a geometric skeleton to generate the surface gives important benefits: • The implicit surface can be computed  ...

Starting from a template of the actor model, we introduce a new unified implicit representation for both, articulated skeleton tracking and nonrigid surface shape refinement.  ...  We propose a new model-based method to accurately reconstruct human performances captured outdoors in a multi-camera setup.  ...  To meet the challenges of less controlled environments, we use a new unified implicit formulation for both, articulated skeleton tracking and non-rigid sur-face shape refinement.  ...
