In the first stage of Wiener filtering, the noisy image is decomposed by SWT. Then, the signal variances of wavelet coefficients are estimated in the elliptic windows. In the second stage of Wiener filtering, the image restored by Inverse SWT is decomposed by DTCWT. Then, the adaptive windows determined by the autocorrelation function of wavelet coefficients` energy distribution are used to estimate the signal variance of wavelet coefficients. Finally, the image is restored by Inverse DTCWT.
