The Meaning of Redundancy - 3D Topology and Geometric Parameterization
ثبت نشده
چکیده
Database normalization is a standard technique to ensure data integrity. Explicitly specified 3D topology as well ensures geometric consistency. This article explains a stepwise reduction of redundancy in the 3D data model. Whereas the topological normalization is well discussed in literature the geometric normalization is a subject to recent research. This approach of data normalization is motivated by the need for applying geodetic adjustment techniques to measured (observed) three-dimensional building models.

A Hybrid 3D Colon Segmentation Method Using Modified Geometric Deformable Models
Introduction: Nowadays virtual colonoscopy has become a reliable and efficient method of detecting primary stages of colon cancer such as polyp detection. One of the most important and crucial stages of virtual colonoscopy is colon segmentation because an incorrect segmentation may lead to a misdiagnosis. Materials and Methods: In this work, a hybrid method based on Geometric Deformable Models...
متن کاملFeature-based 3D morphing based on geometrically constrained spherical parameterization
Current trends in free form editing motivate the development of a novel editing paradigm for CAD models beyond traditional CAD editing of mechanical parts. To this end, we need robust and efficient 3D mesh deformation techniques such as 3D structural morphing. In this paper, we present a feature-based approach to 3D morphing of arbitrary genus-0 polyhedral objects that is appropriate for CAD ed...
متن کاملDiscrete one-forms on meshes and applications to 3D mesh parameterization
We describe how some simple properties of discrete one-forms directly relate to some old and new results concerning the parameterization of 3D mesh data. Our first result is an easy proof of Tutte’s celebrated “springembedding” theorem for planar graphs, which is widely used for parameterizing meshes with the topology of a disk as a planar embedding with a convex boundary. Our second result gen...

متن کاملREDUNDANCY OF MULTISET TOPOLOGICAL SPACES
In this paper, we show the redundancies of multiset topological spaces. It is proved that $(P^star(U),sqsubseteq)$ and $(Ds(varphi(U)),subseteq)$ are isomorphic. It follows that multiset topological spaces are superfluous and unnecessary in the theoretical view point.
