چکیده

A new method of curve-skeleton extraction is proposed in this paper. Unlike most methods this approach retrieves information from a polygonal mesh via rasterization and extraction of silhouettes’ continuous medial axes. Described method shows a great improvement in computational time comparing to existing methods. Method shows good extraction results for models with complex geometry and topology. Resulting curve-skeletons conform with most requirements to universal curve-skeletons.

Practical Medial Axis Filtering for Occlusion-Aware Contours

We propose a filtering system for occlusion-aware contours. Given a point of view, we use the silhouette of a 3D shape from that point of view, its medial axis and a map of the occluded areas. Our filter is able to select the points of the medial axis which are projections of the curve-skeleton of the 3D shape, discarding all the points affected by occlusions. Our algorithm is easy to implement...

PDE-Based Medial Axis Extraction and Shape Manipulation of Arbitrary Meshes

Shape skeletonization (i.e., medial axis extraction) is powerful in many visual computing applications, such as pattern recognition, object segmentation, registration, and animation. In this paper, we expand the use of diffusion equations combined with distance field information to approximate medial axes of arbitrary 3D solids represented by polygonal meshes based on their differential propert...

Flux driven medial curve extraction

In this document it is described the implementation of the flux driven automatic centerline extraction algorithm proposed by Bouix et al. in 2004. This is based on a skeletonisation algorithm initially proposed by Siddiqi et al. in 2002, using properties of an average outward flux measure to distinguish skeletal points from non-skeletal ones. This information is combined with a topology preserv...
