【摘要】 图像的特征增强可以突出地物的空间结构和纹理特征,文中在分析小波变换系数局部特征的基础上,利用系数的局部方差定义了高频融合因子,进行了合成孔径雷达(SAR)图像和光学图像的融合实验。由于对SAR图像进行增强处理,提高了融合图像的细节清晰度,与传统方法进行比较,得到了更好的融合效果。更多还原

【Abstract】 The structure features of SAR image can be improved largely by image enhancement. After analysing the local features of wavlet coefficients, a new methods based on local area variance is introduced, and the method is used to fuse SAR and optical im- ages. Experimental results indicate that this method can obtain more excellent result compared with the traditional method.更多还原
