| 摘 要： | 在介绍遥感图像融合中IHS变换和小波包分析的基础上,提出了一种基于光谱特征保持的IHS变换与小波包分析相结合的图像融合算法。该方法可以最大限度地保留待融合图像的光谱信息,同时融合图像的清晰度和空间分辨率有了很大提高,图像纹理信息也得到了很好的保持。通过对SAR图像与Landsat(TM)多光谱图像的融合实验,证明了该方法的有效性。

| Abstract: | Based on the introduction of IHS transformation in remote sensing image fusion and wavelet packet analysis,this paper puts forward an image fusion algorithm based on the combination of IHS transformation based on spectral feature restore and wavelet packet analysis.This algorithm can retain the spectral information of the fusion image to the greatest extent,greatly improve the definition and spatial resolution of the fusion image,and retain the texture information of the image.The algorithm is proved effective through the experiment of the fusion of SAR image and Landsat(TM) multi-spectra image. |
