“…Since wavelet coefficients having large absolute values contain the information about the salient feature of the images such as edges and lines. Many wavelet based techniques for fusion of 2-D images have been described in the literature [3,4,5,6]. In all wavelet based image fusion schemes the wavelet transforms W of the two registered input images I 1 (x,y) and I 2 (x,y) are computed and these transforms are combined using some kind of fusion rule Φ, Figure(1).…”

“…The method proposed in Ref. 15, uses a zero-mean bivariate Gaussian PDF over the local neighboring detail DWT coe±cients of the input images. Moreover, Loza et al 16 have used Generalized Gaussian (GG) and alpha-stable prior to fuse noisy images.…”

“…The innovative aspect of the present work is twofold:¯rst, we use a trivariate Gaussian PDF as in Ref. 15 for the detail 2D-SMCWT coe±cients while taking into account the mutual correlation between the input images and the fused image. A Bayesian MAP estimation technique has been used to obtain the detail 2D-SMCWT coe±cients of the fused image.…”
