A Multiscale Topographical Analysis Based on Morphological Information: The HEVC Multiscale Decomposition. [PDF]
Materials (Basel), 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 ...

On Dynamical Decomposition of Multiscale Oceanic Motions
Journal of Advances in Modeling Earth Systems, 2023 The ocean hosts a variety of fluid motions characterized by contrasting dynamical regimes and spatiotemporal scales. A practical decomposition of multiscale motions in realistic oceanic settings is crucial to advancing dynamical interpretation and ...

Hybrid Localized Spectral Decomposition for Multiscale Problems [PDF]
SIAM 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
SoftwareX, 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]
Numerische 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 ...
