Non-congruent non-degenerate curves with identical signatures

*JOURNAL OF MATHEMATICAL IMAGING AND VISION*, *63*(5), 601–625.

author keywords: Closed curves; Euclidean transformations; Signature curves; Signature graphs (quivers); Object recognition

TL;DR:
It is shown that while the claim by Hickman holds for simple, closed curves with simple signatures, it fails for curves with non-simple signatures, and congruence criteria for non-degenerate, closed, simple planar curves is formulated.

Differential Signatures of Algebraic Curves

*SIAM Journal on Applied Algebra and Geometry*.

author keywords: algebraic curves; projective action; affine action; Euclidean action; equivalence classes of curves; differential invariants; classifying invariants; signatures; Fermat curves

TL;DR:
The differential signature construction is adapted to the equivalence problem for complex plane algebraic curves under the actions of the projective group and its subgroups and it is proved that for any $G$-action, there exists a pair of rational differential invariants, called classifying invariant, that can be used to construct signatures.
