Figure 1
A schematic diagram of (a) DWT and (b) DWPT with the wavelet level of 3, where Lā2 denotes the half-band low-pass filter and Hā2 denotes the half-band high-pass filter. CAA denotes the approximate representation (scaling coefficients) of CA, CDA denotes the detailed representation (wavelet coefficients) of CA, and so on.
