Hierarchical symmetry segmentation
Alan Laird, James Miller · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1991
We give an introduction to the phenomenon ofsymmetry and briefly describe its importance to machine vision tasks. An algorithm is then presented which finds all axes of local symmetry builds these axes into the axes of subparts and then uses this new set of axes to approximate image features with symmetrical shapes. Finally a hierarchy of such axes is produced.
