Symmetry Set Representation
Symmetry sets or medial axes (or skeletons) are defined as the locus of maximally inscribed bitangent circles
They are used in computer vision, robotics, computational geometry, computer graphics, etc.
Specificially, they are used
as shape descriptors for object recognition [Zhu&Yuille, Kimia, Siddiqi,..]
in simplifying (partitioning or grouping) visual forms [Blum, Ahuja,August, Tek&Kimia]
in image segmentation [Vincent:Soille, Sebastian et al]
in image compression [Brandt:etal]
in path planning [Held]
in statistical clustering [Ahuja]
in finite element meshing [Srinivasan]
in triangulating point sets [Chew]
