Abstract: A new multi-resolution wavelet second image fusion method is proposed based on PCA transform and HIS transform.As follows：Firstly,multi-spectral image are transformed into the HIS space to obtain the first merged image.Secondly,transform original multi-spectral image and the first merged image into three principal components using PCA transform,and then decompose them respectively to appropriate scale with a wavelet filter and merge them with directive contrast merger.Finally,fusion image is obtained by inverse PCA transform.Experimental results indicate that the proposed method perform better in combining and preserving spectral-spatial information,Its objective performance are better than the many other methods.
