I'm performing wavelet anaylsis of a 2D signal, using the continuos wavelet transform.
I need Morlet complex wavelet, so I'm using the AWT.vi.
The vi uses a wavelet definition with a central frequency \omega_0=3\pi/2,
moreover it contains a \sigma value (standard deviation of the Gaussian envelope
of the mother wavelet). How is the value of \sigma?
Thanks

Mr. Bettega,
could you please give me some more information?
Are you using the "WA Analytic Wavelet Transform.vi" of the LabVIEW Advanced Signal Processing Toolkit?
As you probably have seen, in the LabVIEW Help page for this function, there is the definition of the complex Morlet Wavelet (with the relative sigma).
Which information would you like to have about the sigma value? Do you need to know the definition of the mother wavelet?
