基于边缘信息的多光谱高分辨图像融合方法

针对多光谱图像和高分辨图像的融合问题,提出了一种基于边缘信息的新的图像融合 方法,该方法根据高分辨图像中的边缘强度,对多光谱图像在IHS变换中的强度信息进行了调 整,得到的光谱强度同时反映了高分辨图像的细节信息和多光谱图像的光谱信息.实验结果表 明,该方法的融合效果优于传统的IHS变换法和小波变换方法.

A METHOD TO FUSE MULTISPECTRAL AND HIGH RESOLUTION IMAGES BASED ON EDGE INFORMATION

A new technique is developed for data fusion of multispectral image and high resolution image. The intensity component of the fusion image is modified by combining multispectral information and high resolution information which is determined by image edge intensity. The fusion image is reconstructed by means of the inverse IHS transform. Experimental comparisons show that the IHS method performs better in preserving spatial resolutions and color content than the traditional IHS transform technique and wavelet transform fusion method.
