Figure 5From: Automatic detection of mode mixing in empirical mode decomposition using non-stationarity detection: application to selecting IMFs of interest and denoisingResults on the mechanical signal from the ball bearing plus noise. Above: The evolution of the percentage of mean square error (NPMSE) (±σ) as obtained by using the classic method (1), by only correcting the estimate of noise in the first IMF (2) and by correcting the estimate of noise in the first IMF and plus modification of the second IMF (3). Below: Comparison of the NPMSE obtained using the wavelets Daubechie (Daub.), Haar and Meyer.Back to article page
