We present an algorithm that, starting from the surface skeleton of a 3D solid object, computes the curve skeleton. The algorithm is based on the detection of curves and junctions in the surface skeleton. It can be applied to any surface skeleton, including the case in which the surface skeleton is two-voxel thick.

In this paper, we present a novel approach to robust skeleton extraction. We use undirected graphs to model connectivity of the skeleton points. The graph topology remains unchanged throughout the skeleton computation, which greatly reduces sensitivity of the skeleton to noise in the shape outline. Furthermore, this representation naturally defines an ordering of the points along the skeleton. ...

We present a new curve skeleton model designed for surface modeling and processing. This skeleton is defined as the geometrical integration of a piecewise harmonic parameterization defined over a disk-cylinder surface decomposition. This decomposition is computed using a progressive Region Graph reduction based on both geometric and topological criteria which can be iteratively optimized to imp...

Skeleton is an important 1-D descriptor of polygon and a useful tool for advanced geometric algorithms. However the skeleton that most existing algorithms investigated is the longest one, which is not intended in all circumstances. This paper proposes an algorithm for extracting hierarchically optimal skeleton network of polygons. The algorithm incorporates length, angularity and area of associ...

I t pays to have a backup project in case your main research stalls. That's what Alan Hall (now at University College London) and colleagues learned when they set aside their studies on the protein ras and switched to its cousin rho. Their work (starting with Paterson et al., 1990) revealed that rho and related proteins were key regulators of the cell's actin cytoskeleton, and it set the stage ...

In this article, Imam Khomeini’s political theory is investigated with the Lakatos methodology. His methodology confirms the distinction between a hard core or the original skeleton of investments and experimental propositions confirms as a protective belt for the research program. Regarding this, the claim from this article is that if we understand the system of religious knowledge of Imam Kho...

A method of identification of curvature features for shape description and recognition is suggested. The method is based on the relation between local boundary features and the skeleton structure of a plain domain. It uses a continuous boundary-skeleton model of an image. The model consists of a boundary of a polygonal figure approximating a raster image, and a skeleton of the figure. To reveal...
