This conversion was originally done as part of my PhD, in order to better understand wavelets. See that code base for a wavelet-hierarchical B-spline implemenation including multilevel optimizing ...

This project benchmarks the performance of the wasmlets library (which uses wavelib) against other alternatives for the 1-dimensional discrete wavelet transform in ...

Abstract: Current denoising techniques use the classical ortho normal wavelets for decomposition of an image corrupted with additive white Gaussian noise, upon which various thresholding strategies ...

Abstract: The use of hexagonal grids of pixels to represent digital images is a topic that has been studied for decades; however, despite its advantages there is relatively little work done on the ...

ABSTRACT: In this article algebraic multigrid as preconditioners are designed, with biorthogonal wavelets, as intergrid operators for the Krylov subspace iterative methods. Construction of hierarchy ...

We prove that suitable wavelets and scaling functions give characterizations and unconditional bases of the weighted Sobolev space Lp,s (w) with Ap or $A_p^{loc ...

In this paper we investigate spline wavelets on general triangulations. In particular, we are interested in C¹ wavelets generated from piecewise quadratic polynomials. By using the Powell-Sabin ...
