On multiresolution analysis of multiplicityd
Monatshefte für Mathematik, 1997 A multiresolution analysis (MRA) of multiplicity \(d\) of \(L^2({\mathbb{R}}^n)\) is a generalization of the usual MRA, where the sample spaces are generated by a refinable vector of \(d\) functions. The paper is concerned with the multivariate case, where the dilation matrix is \(2I\).

Fast analysis of large finite arrays with a combined multiresolution-SM/AIM approach [PDF]
, 2006 We present a synthesis of the sparse matrix/adaptive integral method (SM/AIM) and the multiresolution (MR) approach for the analysis of electrically large finite arrays, with planar or 3-D radiating elements; the two methods were separately introduced ...

PWNet: An Adaptive Weight Network for the Fusion of Panchromatic and Multispectral Images
Remote Sensing, 2020 Pansharpening is a typical image fusion problem, which aims to produce a high resolution multispectral (HRMS) image by integrating a high spatial resolution panchromatic (PAN) image with a low spatial resolution multispectral (MS) image.

Ising models and multiresolution quad-trees [PDF]
, 2003 We study percolation and Ising models defined on generalizations of quad-trees used in multiresolution image analysis. These can be viewed as trees for which each mother vertex has 2(d) daughter vertices, and for which daughter vertices are linked ...

Generalized non-stationary multiresolution analysis on locally compact zero-dimensional groups with an arbitrary generating sequence [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаWe consider a locally compact zero-dimensional group $(G, \dot+),$ whose coset orders are arbitrary prime numbers. If the orders of the cosets are constant and equal to some prime number, the multiresolution analysis can be constructed by using a ...

Analysis on Multiresolution Mosaic Images [PDF]
IEEE Transactions on Image Processing, 2004 Image mosaicing is the act of combining two or more images and is used in many applications in computer vision, image processing, and computer graphics. It aims to combine images such that no obstructive boundaries exist around overlapped regions and to create a mosaic image that exhibits as little distortion as possible from the original images.

Multiresolution Analysis Adapted to Irregularly Spaced Data
EURASIP Journal on Advances in Signal Processing, 2009 This paper investigates the mathematical background of multiresolution analysis in the specific context where the signal is represented by irregularly sampled data at known locations.

Multiresolution analysis applied to interpretation of seismic reflection data [PDF]
Geofísica Internacional, 2005 We have developed a method of seismic multiresolution analysis based on the discrete wavelet transform. We illustrate the potential use in petroleum exploration of the joint application of multiresolution analysis and seismic attributes for a real case ...

Hermite Transform Based Algorithm for Detection and Classification of High Impedance Faults
IEEE Access, 2022 This work proposes a new algorithm to classify high impedance faults (HIFs) in distribution systems. HIFs can be represented by small current magnitudes with non-linear variations, which complicate their detection in distribution grids.
