Abstract A new algorithm is developed which merges a highresolution images and multispectral images based on the à trousContourlet transform. First, à trousContourlet transform is presents based on the advantages of à trous wavelet transform and Contourlet transform. Then the images to be merged are decomposed by multiresolution based on the IHS transform and à trousContourlet transform. According to the high frequency information, a new algorithm of weighted average is proposed according to its deviation and collection coefficient. Finally, the image is fused by high frequency addition. The experimental results show that better fusion result by the proposed method is acquired compared with the traditional transform methods.
