Figure 4From: Using Peano–Hilbert space filling curves for fast bidimensional ensemble EMD realizationFrom top to bottom: average Fourier transform of IMFs obtained over 100 realizations of bidimensional Gaussian white noise for the three methods. The simulation with (a) the BEEMD algorithm [5], (b) the LSBEEMD algorithm [4], and (c) the PHEEMD algorithm.Back to article page
