Improved bounds for the rate loss of multiresolution source codes [PDF]
We present new bounds for the rate loss of multiresolution source codes (MRSCs). Considering an M-resolution code, the rate loss at the ith resolution with distortion D/sub i/ is defined as L/sub i/=R/sub i/-R(D/sub i/), where R/sub i/ is the rate ...

Matrix-free weighted quadrature for a computationally efficient isogeometric $k$-method
The $k$-method is the isogeometric method based on splines (or NURBS, etc.) with maximum regularity. When implemented following the paradigms of classical finite element methods, the computational resources required by the $k-$method are prohibitive even

Refined limiting imbeddings for Sobolev spaces of vector-valued functions
The authors consider vector-valued Sobolev, Besov, and Triebel-Lizorkin spaces of functions with values in a general Banach space; in general, these spaces may lack the UMD property. The authors prove a refined limiting embedding theorem of the Brézis-Wainger type in the critical case. The main result reads as follows: Theorem 3.

Several Studies on Framelets Derived From Compactly Supported Refinable Vector Functions
Generalizing wavelets by adding desired redundancy and flexibility, framelets (a.k.a. wavelet frames) are of interest and importance in many applications such as image processing and numerical algorithms. Several key properties of framelets are high vanishing moments for sparse multi-scale representation, fast framelet transforms for numerical ...

Subdivision Directional Fields
We present a novel linear subdivision scheme for face-based tangent directional fields on triangle meshes. Our subdivision scheme is based on a novel coordinate-free representation of directional fields as halfedge-based scalar quantities, bridging the ...

On stable refinable function vectors with arbitrary support
This paper studies the stability property of a refinable function vector in the space of \(L^2\) using the transfer operator (also called the transition operator in the literature of wavelets). Generalizing a result of Gundy from scalar refinable functions to refinable function vectors, under conditions such as the existence of a refinable function ...
