A scale-space approach with wavelets to singularity estimation [PDF]
, 2005 This paper is concerned with the problem of determining the typical features of a curve when it is observed with noise. It has been shown that one can characterize the Lipschitz singularities of a signal by following the propagation across scales of the ...

Free-space-coupled wavelength-scale disk resonators
Nanophotonics, 2022 Optical microresonators with low quality factor (Q$Q$) can be efficiently excited by and scatter freely propagating optical waves, but those with high Q$Q$ typically cannot.

A robust nonlinear scale space change detection approach for SAR images [PDF]
, 2013 In this paper, we propose a change detection approach based on nonlinear scale space analysis of change images for robust detection of various changes incurred by natural phenomena and/or human activities in Synthetic Aperture Radar (SAR) images using ...

An extended Hilbert scale and its applications [PDF]
arXiv, 2021 We propose a new viewpoint on Hilbert scales extending them by means of all Hilbert spaces that are interpolation ones between spaces on the scale. We prove that this extension admits an explicit description with the help of $\mathrm{OR}$-varying functions of the operator generating the scale.

Statistical Scale Space Methods
, 2017 The goal of statistical scale space analysis is to extract scale‐dependent features from noisy data. The data could be for example an observed time series or digital image in which case features in either different temporal or spatial scales would be ...

Geographical Analysis: from Distance-based Space to Dimension-based Space [PDF]
arXiv, 2020 The traditional concept of space in geography is based on the notion of distance. Where there is a spatial analysis, there is a distance measurement. However, the precondition for effective distance-based space is that the geographical systems have characteristic scales.

Ambient Noise‐Derived SmS Splitting: A New Approach to Constraining Crustal Radial Anisotropy
Geophysical Research LettersRecent studies have shown that crustal body wave phases, such as PmP or SmS, can be effectively retrieved from ambient noise cross‐correlations. However, few studies have used these phases to constrain crustal structures.

Journal of Mathematical Imaging and Vision, 2010 This paper describes a generalized axiomatic scale-space theory that makes it possible to derive the notions of linear scale-space, affine Gaussian scale-space and linear spatio-temporal scale-space using a similar set of assumptions (scale-space axioms).
