摘　　要：通过分析比较多光谱与高分辨率图像间融合几种常用算法的原理及其优缺点,提出了一种基于边缘增强算子的光谱保持型融合算法,算法首先利用LOG算子对高分辨率图像进行高提升滤波,然后将滤波后高分辨率图像与原高分辨率图像的亮度的比值作为融合图像各光谱值的调节系数。实验结果表明,此算法具有很好的空间分辨率,同时又能较好地保持原有多光谱图像的光谱特性,取得了较好的效果。Based on analysis ofthe principle, advantages and disadvantages ofthe four methods commonly used in fusing high resolution image and multi-spectral image, a new fusion method based on edge enhancement through high-pass filtering algorithm is proposed. Firstly the high resolution image is processed through LOG high-pass filtering algorithm, and then the fusion image spectral is adjusted by the ratio of high resolution and multi-spectral image. Experiment shows that this algorithm could represents almost the same color as the original multi-spectral image and enhances the space detail.
