Entropy-based Time-Varying Window Width Selection for Nonlinear type Time-Frequency Analysis
Yae-lin Sheu, Liang-Yan Hsu, Pi-Tai Chou +1
We propose a time-varying optimal window width (TVOWW) selection scheme to optimize the performance of several nonlinear-type time-frequency analyses, including the reassignment me…
Heart beat classification from single-lead ECG using the Synchrosqueezing Transform
Christophe L. Herry, Martin Frasch, Andrew JE Seely +1
The processing of ECG signal provides a wealth of information on cardiac function and overall cardiovascular health. While multi-lead ECG recordings are often necessary for a prope…
Exploring laser-driven quantum phenomena from a time-frequency analysis perspective: A comprehensive study
Yae-lin Sheu, Hau-tieng Wu, Liang-Yan Hsu
Time-frequency (TF) analysis is a powerful tool for exploring ultrafast dynamics in atoms and molecules. While some TF methods have demonstrated their usefulness and potential in s…
ConceFT: Concentration of Frequency and Time via a multitapered synchrosqueezed transform
Ingrid Daubechies, Yi Wang, Hau-tieng Wu
A new method is proposed to determine the time-frequency content of time-dependent signals consisting of multiple oscillatory components, with time-varying amplitudes and instantan…
Modeling the pulse signal by wave-shape function and analyzing by synchrosqueezing transform
Hau-tieng Wu, Han-Kuei Wu, Chun-Li Wang +4
We apply the recently developed adaptive non-harmonic model based on the wave-shape function, as well as the time-frequency analysis tool called synchrosqueezing transform (SST) to…
When interpolation-induced reflection artifact meets time-frequency analysis
Yu-Ting Lin, Patrick Flandrin, Hau-tieng Wu
While extracting the temporal dynamical features based on the time-frequency analyses, like the reassignment and synchrosqueezing transform, attracts more and more interest in bio-…
Convex Optimization approach to signals with fast varying instantaneous frequency
Matthieu Kowalski, Adrien Meynard, Hau-tieng Wu
Motivated by the limitation of analyzing oscillatory signals composed of multiple components with fast-varying instantaneous frequency, we approach the time-frequency analysis prob…
