Recycling cardiogenic artifacts in impedance pneumography
Yao Lu, Hau-tieng Wu, John Malik
Purpose: Biomedical sensors often exhibit cardiogenic artifacts which, while distorting the signal of interest, carry useful hemodynamic information. We propose an algorithm to rem…
Single-lead f-wave extraction using diffusion geometry
John Malik, Neil Reed, Chun-Li Wang +1
A novel single-lead f-wave extraction algorithm based on the modern diffusion geometry data analysis framework is proposed. The algorithm is essentially an averaged beat subtractio…
Vector Nonlocal Euclidean Median: Principal Bundle Captures The Nature of Patch Space
Chen-Yun Lin, Arin Minasian, Xin Jessica Qi +1
We extensively study the rotational group structure inside the patch space by introducing the fiber bundle structure. The rotational group structure leads to a new image denoising…
Wave-shape function analysis -- when cepstrum meets time-frequency analysis
Chen-Yun Lin, Li Su, Hau-tieng Wu
We propose to combine cepstrum and nonlinear time-frequency (TF) analysis to study mutiple component oscillatory signals with time-varying frequency and amplitude and with time-var…
Latent common manifold learning with alternating diffusion: analysis and applications
Ronen Talmon, Hau-tieng Wu
The analysis of data sets arising from multiple sensors has drawn significant research attention over the years. Traditional methods, including kernel-based methods, are typically…
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…
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…
A new time-frequency method to reveal quantum dynamics of atomic hydrogen in intense laser pulses: Synchrosqueezing Transform
Yae-lin Sheu, Liang-Yan Hsu, Hau-tieng Wu +2
This study introduces a new adaptive time-frequency (TF) analysis technique, synchrosqueezing transform (SST), to explore the dynamics of a laser-driven hydrogen atom at an {\it ab…
