Building 3D Shapes from Parts
The research described in this thesis has focused on the composition of novel 3D shapes (e.g., depth maps and triangulated meshes) by reusing parts of existing shapes. Specifically, two methods were designed [28, 27]. The first is a novel tool for easy composition of existing 3D models (i.e., triangulated meshes) into novel models [28]. This tool was designed with the intention of providing a m...

In this invited paper, an overview of techniques developed at the Cardiovascular Image Analysis Laboratory at Washington University is discussed. At the core of our methodologies lie exible shape models, which are employed in automated as well as semi-automated analysis of cardiac MRI and X-ray angiog-raphy images. The mathematical bases used for the exible templates are of the B-spline variety...
متن کاملDistributed boundary tracking using alpha and Delaunay-Cech shapes
For a given point set S in a plane, we develop a distributed algorithm to compute the α−shape of S. α−shapes are well known geometric objects which generalize the idea of a convex hull, and provide a good definition for the shape of S. We assume that the distances between pairs of points which are closer than a certain distance r > 0 are provided, and we show constructively that this informatio...
