The Uniqueness of Shift-Generated Duals for Frames in Shift-Invariant Subspaces

TL;DR: In this article, the uniqueness of SG-dual frames is characterized using the Gramian and dual Gramian operators, which were introduced by Ron and Shen and are known to play an important role in the theory of shift-invariant spaces.
Journal ArticleDOI

Properties of oblique dual frames in shift-invariant systems

TL;DR: Gramian analysis is used to study properties of a shift-invariant system X = { ϕ ( ⋅ − B k ) : ϕ ∈ Φ, k ∈ Z n }, where B is an invertible n × n matrix and Φ a finite or countable subset of L 2 ( R n ) under the assumption that the system forms a frame for the closed subspace M of L R n as discussed by the authors.
Journal ArticleDOI

Online Handwritten Signature Verification and Recognition Based on Dual-Tree Complex Wavelet Packet Transform.

TL;DR: A novel procedure for online signature verification and recognition based on Dual-Tree Complex Wavelet Packet Transform (DT-CWPT) is presented, and favorable experimental results confirm the effectiveness of the presented method in both online signature verify and recognition objects.
Journal ArticleDOI

B-spline operational matrix of fractional integration

TL;DR: In this article, the second and third order spline functions are used to derive the operational matrix of fractional integration, which is then applied to solve fractional integro-differential equations, Abel equations and partial fractional differential equations.
Journal ArticleDOI

Numerical solution of two-dimensional first kind Fredholm integral equations by using linear Legendre wavelet

TL;DR: A numerical method is presented for solving two-dimensional first kind Fredholm integral equation based upon two- dimensional linear Legendre wavelet basis approximation by applying tensor product of one-dimensional linear Legend re wavelet.
