Finally, the denoised image is obtained after image reconstruction via inverse wavelet transform [14].
Finally, the fused multi-spectral image is obtained by inverse wavelet transform and inverse IHS transform respectively.
Four methodologies were applied for this: inverse derived (ID), inverse Fourier transform (IFT), inverse discrete cosine transform (IDCT), and inverse wavelet transform (IWT).

6) Use Key to randomly permute coefficients and sub-bands 7) Embed Msg pixels into coefficients of the selected sub-band (s) using the following parameterization function: [Stego.sup.s.sub.x,y] = 2/[beta] (Msg + i), 2i/[beta] [less than or equal to] [Cover.sup.s.sub.x,y] 8) Apply inverse wavelet transform on resultant Stego coefficients.
In this case, during inverse wavelet transform lower/higher values are to be clipped and the secret message bits eventually will be lost.
The inverse wavelet transform can be defined so that x(t) can be reconstructed by means of the formula
This is required to obtain the inverse wavelet transform given by
