Title: SKEW-SYMMETRY DETECTION VIA INVARIANT SIGNATURES.
Authors: AM Bruckstein and D. Shaked
PDFCIS9419.pdf
Abstract: We propose a new approach to skew-symmetry detection, based on the theory of invariant signatures for planar objects. Invariant signatures associated with object boundaries are generalizations of the curvature vs. arclength description of curves, invariant under geometric transformation more complex than the Euclidean ones. We show that symmetries of objects, and hence of closed boundaries, translate into simple structures in the invariant signature functions and are therefore readily detectable.
