  Image fusion produces a single fused image from a set of input images. A new
method for image fusion is proposed based on Weighted Average Merging Method
(WAMM) in the NonSubsampled Contourlet Transform (NSCT) domain. A performance
analysis on various statistical fusion rules are also analysed both in NSCT and
Wavelet domain. Analysis has been made on medical images, remote sensing images
and multi focus images. Experimental results shows that the proposed method,
WAMM obtained better results in NSCT domain than the wavelet domain as it
preserves more edges and keeps the visual quality intact in the fused image.
