Abstract:

Skeletons, or medial axes, have been commonly used in object
representation and recognition. In this talk I will discuss new methods
for generating skeletons of discrete volumes, and explore their
applications in medical imaging and geometry processing for shape and
topology analysis. In particular, I will show how skeletons are used in
identifying secondary structures from low-resolution protein images, as
well as in removing excess topology from large polygonal models
reconstructed from range images created by 3D scanners.
