摘    要:提出一种将IHS变换和小波变换相结合的图像融合算法,适用于多光谱图像和高分辨率图像的融合.算法首先对多光谱图像进行IHS变换,之后利用变换后得到的强度分量和高分辨图像具有较强的相关性的特点,在小波变换域进行图像融合,得到了同时具有较好的空间分辨率和光谱信息的融合图像.实验对比数据表明该方法具有较好的融合效果,融合图像优于传统的IHS变换法和传统小波变换方法.

Abstract:An efficient method of image fusion based on IHS .transform incorporating with wavelet transform to fusion a multi-spectral image and a high resolution image is proposed in this paper. Firstly, the multi -spectral image is transformed by IHS transform, and I, H and S components are obtained; Secondly, the high resolution image and I component of the multi-spectral image are merged with WT - based fusion method, and I component is replaced by the merged data; Finally, the fused image is obtained by inverse IHS transform. The experiment results show that the method is better than those of IHS transform-based fusion method and WT-based method.
Keywords:image fusion  IHS transform  wavelet transform
