Invariance Properties of Generalized Polarization Tensors and Design of Shape Descriptors in Three DimensionsHabib Ammari, Daewon Chung, Hyeonbae Kang et al.
We derive transformation formulas for the generalized polarization tensors under rigid motions and scaling in three dimensions, and use them to construct an infinite number of invariants under those transformations. These invariants can be used as shape descriptors for dictionary matching.
