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.
The composite coefficients of the fused image are subsequently recovered via the total variation optimization (TV) algorithm [14] and inverse wavelet transform.
Four methodologies were applied for this: inverse derived (ID), inverse Fourier transform (IFT), inverse discrete cosine transform (IDCT), and inverse wavelet transform (IWT).
The transmitter side of WOFDM system offers encoding followed by an interleaving along with modulation and Inverse Wavelet Transform (IWT).
(7) After the quantization of HL3 coefficients, the watermarked image could be obtained by the inverse wavelet transform.
From equation (4) it can be deduced that the modulation process consists in performing an inverse wavelet transform to two scales on the symbols to be transmitted, that is, assuming that these symbols correspond to the wavelet coefficients of the modulated signal.

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
