on the Influence of Sampling on the Empirical Mode Decomposition [PDF]

open access: yes2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
The rationale underlying the nonlinear Empirical Mode Decomposition method is intrinsically a continuous-time approach. The method can however only be applied in practice to discrete-time signals. EMD is obtained through iterating a basic nonlinear operator for which we derive an upper bound for the effects of sampling.

Composite fault diagnosis of gearbox based on empirical mode decomposition and improved variational mode decomposition

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
In order to identify the nonlinear nonstationary pitting-wear fault signal of gears in gearbox, a new method of composite fault diagnosis for gearbox is proposed, which combines empirical mode decomposition with improved variational mode decomposition ...

A pixel-level entropy-weighted image fusion algorithm based on bidimensional ensemble empirical mode decomposition

open access: yesInternational Journal of Distributed Sensor Networks, 2018
The bidimensional empirical mode decomposition algorithm is more suitable to handle image fusion than the traditional multi-scale decomposition methods in the image fusion area.

A comparative study of single-channel signal processing methods in fetal phonocardiography.

open access: yesPLoS ONE, 2022
Fetal phonocardiography is a non-invasive, completely passive and low-cost method based on sensing acoustic signals from the maternal abdomen. However, different types of interference are sensed along with the desired fetal phonocardiography.

A Comparative Study of Empirical and Variational Mode Decomposition on High Voltage Discharges

open access: yesElectrica, 2018
Signal quality is the keyissue for maintaining effective power transmission in electrical networks. Inmost cases, a high voltage (HV) is transmitted in power systems to decreasepower loss.

Empirical mode decomposition on surfaces

open access: yesGraphical Models, 2012
Empirical Mode Decomposition (EMD) is a powerful tool for analysing non-linear and non-stationary signals, and has drawn a great deal of attentions in various areas. In this paper, we generalize the classical EMD from Euclidean space to the setting of surfaces represented as triangular meshes.
