Hybrid Localized Spectral Decomposition for Multiscale Problems [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2021
We consider a finite element method for elliptic equation with heterogeneous and possibly high-contrast coefficients based on primal hybrid formulation. A space decomposition as in FETI and BDCC allows a sequential computations of the unknowns through elliptic problems and satisfies equilibrium constraints.

EPT: An R package for ensemble patch transform

open access: yesSoftwareX, 2021
The primary focus of multiscale analysis is to interpret the temporal characteristics of one-dimensional signals and local spatial patterns of two-dimensional images according to the scale variability.

Domain decomposition for multiscale PDEs [PDF]

open access: yesNumerische Mathematik, 2007
The authors consider additive Schwarz domain decomposition preconditioners for piecewise linear finite element approximations of elliptic partial differential equations with highly variable coefficients. These preconditioners combine local solvers on general overlapping subdomains together with a global solver on a general coarse space of functions on ...

Infrared and visible image fusion via octave Gaussian pyramid framework

open access: yesScientific Reports, 2021

Multiscale Analysis of Runoff Complexity in the Yanhe Watershed

open access: yesEntropy, 2022
Runoff complexity is an important indicator reflecting the sustainability of a watershed ecosystem. In order to explore the multiscale characteristics of runoff complexity and analyze its variation and influencing factors in the Yanhe watershed in China ...

Multiscale Decompositions of Hardy Spaces

open access: yes, 2022
An inspiration at the origin of wavelet analysis (when Grossmann, Morlet, Meyer and collaborators were interacting and exploring versions of multiscale representations) was provided by the analysis of holomorphic signals, for which the images of the phase of Cauchy wavelets were remarkable in their ability to reveal intricate singularities or dynamic ...

Fusion of Panchromatic and Multispectral Images Using Multiscale Convolution Sparse Decomposition

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
In this article, we proposed a novel image fusion method based on multiscale convolution sparse decomposition (MCSD). A unified framework based on MCSD is first utilized to decompose panchromatic (PAN) image and the spatial component of upsampled low ...

A Multiscale Topographical Analysis Based on Morphological Information: The HEVC Multiscale Decomposition [PDF]

open access: yesMaterials, 2020
In this paper, we evaluate the effect of scale analysis as well as the filtering process on the performances of an original compressed-domain classifier in the field of material surface topographies classification. Each surface profile is multiscale analyzed by using a Gaussian Filter analyzing method to be decomposed into three multiscale filtered ...

An Adaptive Multiscale Gaussian Co-Occurrence Filtering Decomposition Method for Multispectral and SAR Image Fusion

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Spectral information and backscatter information are both exclusively important bases for land cover classification, and these two kinds of information are found in multispectral images and SAR images, respectively. Therefore, the fusion of complementary
