Multiscale image fusion methods based on wavelet-domain

A multiscale image fusion method based on wavelet-domain is presented.Different fusion rules are adopted in high-frequency detailed parts and low-frequency approximate parts to overcome the disadvantages in image fusion which are easily disturbed by noise and subjected to loss of detailed imformation.At last,this paper compares the image fusion result with traditional wavelet image fusion and image fusion based on PCA methods through simulation,proving the effectiveness of the new algorithm.
