Invariance Signatures: Characterizing Contours by Their Departures from Invariance
In this paper, a new invariant feature of two-dimensional contours is reported: the Invariance Signature. The Invariance Signature is a measure of the degree to which a contour is invariant under a variety of transformations, derived from the theory of Lie transformation groups. It is shown that the Invariance Signature is itself invariant under shift, rotation and scaling of the contour. Since...
متن کاملHomotopy invariance of higher signatures
We prove that the higher signature for any close oriented manifold is a homotopy invariant. 2000 MR Subject Classification 57N70, 57R95, 57R40
متن کاملSize-distance invariance: kinetic invariance is different from static invariance.
The static form of the size-distance invariance hypothesis asserts that a given proximal stimulus size (visual angle) determines a unique and constant ratio of perceived object size to perceived object distance. A proposed kinetic invariance hypothesis asserts that a changing proximal stimulus size (an expanding or contracting solid visual angle) produces a constant perceived size and a changin...
متن کاملInvariance of Fréchet frames under perturbation
Motivating the perturbations of frames in Hilbert and Banach spaces, in this paper we introduce the invariance of Fr'echet frames under perturbation. Also we show that for any Fr'echet spaces, there is a Fr'echet frame and any element in these spaces has a series expansion.
متن کاملConcordance Invariance of Levine-Tristram Signatures of Links
We determine for which complex numbers on the unit circle the Levine-Tristram signature and the nullity give rise to link concordance invariants. 2010 Mathematics Subject Classification: primary: 57M25, secondary: 57M27, 57N70
