基于IHS变换和小波变换相结合的IKONOS影像融合技术

Integrated Technique for IKONOS Image Fusion Combining IHS Transformati on and Wavelet Transformation Algorithms

为了充分利用各种遥感影像的信息,基于多分辨率小波融合的融合方法在近几年来得到了广泛的应用。针对IKONOS卫星的全色波段和多光谱波段的影像,提出了一种基于IHS变换和小波变换结合的影像融合方法。对比实验表明了这种结合两种变换的融合方法能够有效保持IKONOS卫星全色影像高空间分辨率的同时,且能较好地保留多光谱影像的光谱信息。

In order to mining deeply the information of remote sensing images, various methods of multi-resolution wavelet transformation for image fusion have been applied widely in recent years. An integrated technique combining IHS transformation and wavelet transformation methods is proposed in this paper,in order to processing IKNOS panchromatic image and multi-spectral images. Based on the evaluation of comparing tests, it is proved that the new proposed method could preserve multi-spectral information exactly as well as strengthening spatial resolution of IKONOS images effectively.
