A Few Examples of Pictures (Using MATLAB or c++):
Fig.54 Wigner Distribution of Matching Pursuit Time-frequency atoms in the Phase plane of an arbitrary signal (according to Mallat-Zhang developments,98).
The signal is composed of: 1.One short sine (at the beginning), 2.Two Gabor functions, 3.One dirac function, 4.A noise along the signal.
Fig.55 Same Data as before but shown in three dimension. Note the transverse line corresponding to the noise that has been added to the signal.
Fig.56 Wigner Distribution of Matching Pursuit waveform atoms in the Time-Frequency plane for the signal "transients" (512 data).
Fig.56 Same as before but with the relief expressing the amplitude.
Fig.58 Same as before but with relief, elevation and azimut.
Fig.59 Wigner Distribution of Matching Pursuit waveform atoms in the Time-Frequency plane for the logistic map in the chaotic domain (512 data).
Fig.60 Same as before (colormap jet version).
