摘要：The objective of image fusion is to combine information from multiple images of the same scene. The result of image fusion is a new image which is more suitable for human and machine perception or further image-processing tasks such as segmentation, feature extraction and object recognition. The major drawback of the contourlet transform is that its basic images are not localized in the frequency domain and less regula rity in spatial domain. In the current, we analyse the cause of this problem, and propose a new contourlet construction as a solution. So, instead of using the Laplacian pyramid, we employ a new multi-scale decomposition defined in the frequency domain so that the resulting basis images are sharply localized in the frequency domain and exhibit smoothness along their main ridges in the spatial domain. It forms a multi resolution directional tight frame designed to efficiently approximate images made of smooth regions separated by smooth boundaries
