Signal Processing Methods (Wavelet Families)
In order to select the appropriate wavelet family, all
continuous wavelet families in the MATLAB wavelet toolbox
were tested whereby BIOR2.4 (a = 96), COIF2 (a = 100), DB3
(a = 76) and HAAR (a = 54) were found to be the optimal
signal processing methods to reach the highest recovery
results, where a represents the scale factor.
The problem with this approach was that for each wavelet
family we had to repeat the calculations within the same
family, as well as among the wavelet families, in order to
obtain the highest recovery results. In other words, the
optimization procedure had to be used which we did manually.
It should be noted that the results yielded by the wavelet
families also depended on the analyzed data.
After transferring the original absorption data vectors onto
the continuous wavelet domain, we processed the data via the
above-proposed families and under the above-mentioned
optimal conditioons.CWT coefficients spectra of TMP and
SMX compounds were obtained by plotting the CWT
