Hi Marc,

There are two approaches you can take. Since the wavelet transform is just a
convolution, you can use a deconvolution (or the inverse FFT if you are
doing this via FFT). However, an even simpler approach is to just sum the
real part (if complex) of the wavelet transform over all scales, and apply
an appropriate scaling factor. The scaling factor depends upon the scale,
the time sampling, and your wavelet function.

For details, I would recommend looking at Torrence and Compo, 1998: A
Practical Guide to Wavelet Analysis, available at
http://paos.colorado.edu/research/wavelets/

Hope this helps.
