一种Curvelet变换和IHS变换相结合的遥感图像融合方法

根据图像处理中所用的不同数学模型的特点,提出了一种Curvelet变换和IHS变换相结合的遥感图像融合方法。首先对多光谱图像进行IHS变换,然后利用Curvelet变换对I分量和高分辨率图像进行融合,最后进行IHS逆变换,得到融合结果图像。结果表明,该方法在保持源数据光谱特性方面优势突出,其融合结果可以应用于以光谱分析为主的领域。

A Remote Sensing Image Fusion Method based on Curvelet Transform and IHS Transform

Based on the features of the different mathematical models during the image processing,we proposed a remote sensing image fusion method,which is based on Curvelet transform and IHS transform.Firstly,the IHS transform is applied to multi-spectral image;then,the I component and the high-resolution image are fused through Curvelet transform;finally,we can obtain the result by inverse IHS transform.The experimental results show that the method has outstanding advantages,which maintain the spectral characteristi...
