基于引导滤波的遥感图像融合算法

针对目前遥感图像融合算法的不足，提出了一种基于引导滤波的遥感图像融合算法。该算法通过引导滤波器求取加权系数，对小波变换后的小波系数和近似系数进行加权融合，针对融合后得到的小波系数和近似系数应用小波反变换，最终得到融合图像。实验结果表明，文中提出的融合算法所得图像内容丰富、细节清晰、具有良好的实验效果。

Remote Sensing Image Fusion Algorithm Based on Guided Filtering

A guided filtering based remote sensing images fusion algorithm is presented in this paper. Weighted coefficients are determined with guided filter, wavelet coefficients and approximation coefficients are fused by the weighted fusion method. A fused image is obtained by inverse wavelet transform. Experiment results show that the fused image based on the proposed algorithm contains a great amount of information with clear details.
