Ridge detection for nonstationary multicomponent signals with time-varying wave-shape functions and its applications

Yan-Wei Su, Gi-Ren Liu, Yuan-Chung Sheu +1

We introduce a novel ridge detection algorithm for time-frequency (TF) analysis, particularly tailored for intricate nonstationary time series encompassing multiple non-sinusoidal…

Gaussian Approximation for the Moving Averaged Modulus Wavelet Transform and its Variants

Gi-Ren Liu, Yuan-Chung Sheu, Hau-Tieng Wu

The moving average of the complex modulus of the analytic wavelet transform provides a robust time-scale representation for signals to small time shifts and deformation. In this wo…
