Multiresolution vector quantization [PDF]
, 2004 Multiresolution source codes are data compression algorithms yielding embedded source descriptions. The decoder of a multiresolution code can build a source reproduction by decoding the embedded bit stream in part or in whole.

Interpolating refinable function vectors with reflection properties
Journal of Computational and Applied Mathematics, 2016 A refinable function vector \(\Phi=(\phi_1,\ldots,\phi_r)^T\) satisfies an refinement equation: \[ \Phi(x)=N\sum_{k\in \mathbb{Z}} P_k \Phi(Nx-k) \] for a finitely supported sequence \(\{P_k\}_{k\in \mathbb{Z}}\) and a positive integer \(N>1\). In this paper, the authors consider a special family of refinable function vectors \(\Phi\) having the ...

Complete measurements of quantum observables
, 2012 We define a complete measurement of a quantum observable (POVM) as a measurement of the maximally refined version of the POVM. Complete measurements give information from the multiplicities of the measurement outcomes and can be viewed as state ...

Symmetric interpolatory dual wavelet frames [PDF]
, 2014 For any symmetry group $H$ and any appropriate matrix dilation we give an explicit method for the construction of $H$-symmetric refinable interpolatory refinable masks which satisfy sum rule of arbitrary order $n$.

Strong Successive Refinability and Rate-Distortion-Complexity Tradeoff
, 2016 We investigate the second order asymptotics (source dispersion) of the successive refinement problem. Similarly to the classical definition of a successively refinable source, we say that a source is strongly successively refinable if successive ...

A Matricial Algorithm for Polynomial Refinement [PDF]
, 2011 In order to have a multiresolution analysis, the scaling function must be refinable. That is, it must be the linear combination of 2-dilation, $\mathbb{Z}$-translates of itself. Refinable functions used in connection with wavelets are typically compactly

A REFINEMENT OF GRÜSS TYPE INEQUALITY FOR THE BOCHNER INTEGRAL OF VECTOR-VALUED FUNCTIONS IN HILBERT SPACES AND APPLICATIONS [PDF]
Journal of the Korean Mathematical Society, 2006 A refinement of Gruss type inequality for the Bochner integral of vector-valued functions in real or complex Hilbert spaces is given. Related results are obtained. Application for finite Fourier transforms of vector-valued functions and some particular inequalitites are provided.

Improved bounds for the rate loss of multiresolution source codes [PDF]
, 2003 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 ...
