چکیده

Let W (ψ; x, y) be the wideband ambiguity function. It is obtained in this note that y− α+2 2 W (ψ;x, y)(α > −1) is SO(2)-invariant if and only if the Fourier transform of ψ is a Laguerre function.

Application of Polar Harmonic Transforms to Fingerprint Classification

Accurate object classification is often confounded by the variation of the pose of the object. We show in this chapter how a set of recently introduced transforms, called the Polar Harmonic Transforms (PHTs), can be used to produce a set of features for rotation invariant fingerprint representation. For accurate classification, fingerprint images often need to be corrected for rotational differ...

Pseudo Zernike Moment-based Multi-frame Super Resolution

The goal of multi-frame Super Resolution (SR) is to fuse multiple Low Resolution (LR) images to produce one High Resolution (HR) image. The major challenge of classic SR approaches is accurate motion estimation between the frames. To handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...

Gauge Fixing on the Lattice without Ambiguity

A new gauge fixing condition is discussed, which is (lattice) rotation invariant, has the ‘smoothness’ properties of the Landau gauge but can be efficiently computed and is unambiguous for almost all lattice gauge field configurations. ∗on leave from HLRZ c/o KFA Jülich, P.O.

Invariant functions for solving multiplicative discrete and continuous ordinary differential equations

In this paper, at first the elemantary and basic concepts of multiplicative discrete and continous differentian and integration introduced. Then for these kinds of differentiation invariant functions the general solution of discrete and continous multiplicative differential equations will be given. Finaly a vast class of difference equations with variable coefficients and nonlinear difference e...
