Computing skeletons in three dimensions
Skeletonization will probably become as valuable a tool for shape analysis in 3D, as it is in 2D. We present a topology preserving 3D skeletonization method which computes both surface and curve skeletons whose voxels are labelled with the D6 distance to the original background. The surface skeleton preserves all shape information, so (close to) complete recovery of the object is possible. The ...
متن کاملSkeletons in N dimensions using shape primitives
This paper describes the generation of shape primitive detecting masks and their application in measurements on shapes as well as in conditions for topology preservation as used in skeletonization. The formalism is expanded from twoto four-dimensional images and elaborates on the extension of 3D skeletonization to 4D skeletonization. 2002 Elsevier Science B.V. All rights reserved.
متن کاملGeodesic grassfire for computing mixed-dimensional skeletons
Skeleton descriptors are commonly used to represent, understand and process shapes. While existing methods produce skeletons at a fixed dimension, such as surface or curve skeletons for a 3D object, often times objects are better described using skeleton geometry at a mixture of dimensions. In this paper we present a novel algorithm for computing mixed-dimensional skeletons. Our method is guide...
متن کاملComputing Stable Skeletons with Particle Filters
We present a novel method to obtain high quality skeletons of binary shapes. The obtained skeletons are connected and one pixel thick. They do not require any pruning or any other post-processing. The computation is composed of two major parts. First, a small set of salient contour points is computed. We use Discrete Curve Evolution, but any other robust method could be used. Second, particle f...
متن کاملThree-dimensional Straight Skeletons from Bisector Graphs
A straight skeleton of a polygon or of a polytope is a piecewise linear skeletal structure that partitions the underlying object by means of a self-parallel shrinking process. We propose a method for constructing different straight skeletons for a given nonconvex polytope Q in 3-space. The approach is based on so-called bisector graphs on the sphere, and allows for generating straight skeletons...
