【摘要】 提出了一种基于高通滤波的多光谱图像与高空间分辨率图像融合的方法。该算法首先对高空间分辨率图像进行高通滤波,然后将滤波后的图像与HIS正变换后的强度分量进行融合处理,再进行HIS逆变换,得到最后的融合图像。通过将小波方法与HIS变换法的融合结果进行对比评价,表明了该方法在提高多光谱图像的空间细节表现能力和保持光谱信息上都有很好的效果。更多还原

【Abstract】 This paper developed a new method based on high pass filter for the fusion of a high spatial resolution image and a low-resolution,multi-spectral image.The algorithm filtered on a high spatial resolution image with high pass filter,fused the image with the intensity component obtained by HIS transform,reconstructed merged image by an inverse HIS transform.Compared with WT and HIS,this algorithm is more efficient in preserving spectral and improving spatial presentation.更多还原
