摘　　要：将多分辨率分析融合方法和多尺度几何分析融合方法应用于DMSP气象卫星夜间微光云图和红外云图的融合中,并对各种融合算法的性能进行了客观评价。融合实验结果显示,融合图像与源图像相比取得了良好的视觉效果。从平均互信息和Xydeas-Petrovic指标看,拉普拉斯金字塔融合算法和非下采样Contourlet融合算法的融合效果较其他方法优越。The multi-resolution analysis fusion method and multi-scale geometric analysis fusion method are employed in the fusion of meteorological satellite DMSP nighttime visible image and infrared image,and the evaluations of the performance of different algorithms are made.The results show that the visual effect of fused images are actually improved relative to visible images and infrared images after image fusion.From the two objective evaluation indexes,the Laplacian pyramid algorithm and nonsubsampled contourlet transform algorithm＇s performance are better than the other algorithms.
