Fully Adaptive Time-Varying Wave-Shape Model: Applications in Biomedical Signal Processing
Joaquin Ruiz, Gastón Schlotthauer, Leandro Vignolo +1
In this work, we propose a time-varying wave-shape extraction algorithm based on a modified version of the adaptive non-harmonic model for non-stationary signals. The model codifie…

Wave-shape Function Model Order Estimation by Trigonometric Regression
Joaquin Ruiz, Marcelo A. Colominas
The adaptive non-harmonic (ANH) model is a powerful tool to compactly represent oscillating signals with time-varying amplitude and phase, and non-sinusoidal oscillating morphology…

An iterative warping and clustering algorithm to estimate multiple wave-shape functions from a nonstationary oscillatory signal
Marcelo A. Colominas, Hau-Tieng Wu
Nonsinusoidal oscillatory signals are everywhere. In practice, the nonsinusoidal oscillatory pattern, modeled as a 1-periodic wave-shape function (WSF), might vary from cycle to cy…
