As a result of the decomposition in the RGB layers, four subbands are obtained, corresponding to the approximation coefficients (LLSI), the horizontal detail coefficients (LHSI), the vertical detail coefficients (HLSI), and the diagonal detail coefficients (HHSI).
Once the first level of wavelet decomposition is applied, the corresponding subbands are obtained, in the case of subband LHSI, where the recovery map is stored, which allows us to identify the areas where the information of the IO is stored.
