By the term discrete wavelet transform, we mean, in fact, the continuous wavelets with the discrete
scale and translation factors. The wavelet transform is then evaluated at discrete scales and translations.
The discrete scale is expressed as s = s0
i
, where i is integer and s0 > 1 is a fixed dilation step. The discrete
translation factor is expressed as τ = kτ0s0
i
, where k is an integer. The translation depends on the dilation
step, s0
i
. The corresponding discrete wavelets are written as:
