Curve-skeletons are thinned 1D representations of 3D
objects useful for many visualization tasks including
animation, virtual navigation, reduced-model formulation,
visualization improvement, medical imaging, and perceptual tasks. There are
many algorithms in the literature describing extraction
methodologies for different applications; however, it is
unclear how general and robust they are. In this talk, we
will provide an overview of many curve-skeleton applications as well as
various classes of algorithm. We will also discuss a taxonomy of methods and
analyze the advantages and drawbacks of each class of
algorithms.
