3. Discrete WT

Contrarily to both the continuous wavelet transform and the pseudo-affine Wigner transform menus, you may here input 1D or 2D signals, and get their discrete wavelet transform. As said in the overview, this window is exactly the same as the one that appears in the 1D Multifractal Spectra estimation menu (except in the 1D Multifractal Spectra estimation menu you cannot compute transforms of images). Briefly, select first your Input Signal using the Refresh button. You may then choose the analyzing Wavelet from a choice of various Daubechies and Coiflet wavelets. Specify next the number of Octaves, i.e. on how many scale levels you wish to perform the analysis. On pressing Compute, the output signal dwt_sig# will be created.
