| 摘 要： | 提出了一种基于分层图像融合的合成孔径雷达(Synthetic Aperture Radar,SAR)图像可视化增强方法。根据SAR图像特点,通过图像灰度级分层、融合等处理,并在图像融合时加入动态范围约束条件进行求解,对SAR图像做了可视化增强处理,处理得到的图像动态范围满足显示打印等设备动态范围约束条件,且与常规方法相比能更多地保留原图细节信息。实验结果表明了本文方法的有效性。

| Abstract: | A new SAR image visual enhancement algorithm is developed based on image hierarchical fusion.According to the character of SAR image,the algorithm segments the image into several images which contain some gray-levels respectively.Then a result image is fused out using these images,within the condition of dynamic range constraint.The result image's dynamic range satisfies the constraint condition of display/print devices.Also compared with the traditional methods,more detail information of original image is retained.Experimental results verify the effectiveness of this algorithm. |
