【Abstract】 Image fusion is one of the important techniques to enhance image information of remote sensing. How to make efficient data fusion for multi-source remote sensing image of the same object, make the best of the useful information, improve the system’s ability of correct recognition, judgement and decision, is an important aspect of data fusion research. This paper introduces one image data fusion method based on wavelet transformation. In the fusion image, all the multi-spectral characteristics have been preserved, and the definition and the spatial quality of multi-spectral image have been improved. The results were fully analyzed and discussed. Satisfactory effect has been obtained while applying MATLAB language to analyze the result of the experiments.更多还原
