Skeleton pruning as trade-off between skeleton simplicity and reconstruction error

Skeleton Pruning by Contour Partitioning

In this paper, we establish a unique correspondence between skeleton branches and subarcs of object contours. Based on this correspondence, a skeleton is pruned by removing skeleton branches whose generating points are on the same contour subarc. This has an effect of removing redundant skeleton branches and retaining all the necessary visual branches. We show that this approach preserves skele...

Skeleton growing and pruning with bending potential ratio

We propose a novel significance measure for skeleton pruning, called bending potential ratio (BPR), in which the decision regarding whether a skeletal branch should be pruned or not is based on the context of the boundary segment that corresponds to the branch. By considering this contextual information, we can better evaluate the contribution of the boundary segment to the overall shape, which...

Terrain Reconstruction from Contours by Skeleton Construction

Generating terrain models from contour input is still an important process. Most methods have been unsatisfactory, as they either do not preserve the form of minor ridges and valleys, or else they are poor at modelling slopes. A method is described here, based on curve extraction and generalization techniques, that is guaranteed to preserve the topological relationships between curve segments. ...

3D Reconstruction Method for the Head Skeleton

3D representation of surfaces and volumes is considered to be an important investigation method. The surfaces and volumes built on the base of 2D images, issued from computed tomography (CT) or magnetic resonance (MR) investigations, are very helpful for a correct diagnose. The paper proposes an original method for 3D reconstruction, based on 2D image acquisition, applicable to all types of hum...
