Abstract

The goal of image fusion is to combine a high quality image from multi-images of the same object. The paper presents an image fusion scheme based on wavelet transform. Firstly, the large-scale land-use image is decomposed by orthogonal wavelet; secondly, the approximate low-frequency information just decomposed with the small-scale land-use image is replaced; finally the fused image is obtained by taking inverse wavelet transform. The fused land-use image obtains the merits of the images which have different scales. This scheme realizes that the information of spatial objects increases or decreases automatically with the differences of the scales.
