| 摘 要： | 提出了一种基于区域特征动态加权的自适应遥感图像融合方法。该方法首先由输入图像得到其高频、低频图像；进而分别选取一组区域特征进行自适应动态加权，得到相应的高频和低频融合结果；最后，基于一致性准则由高低频融合结果得到最终的融合结果，通过对SAR和TM图像的融合实验，验证了该方法在信息量，边界保持及融合结果一致性方面具有显著优势。 |

| Abstract: | In this paper, a self adaptive fusion method based on dynamic weighting of regional features is proposed. Firstly, each original image is divided into high frequency and low frequency images, according to which, a set of regional features are extracted respectively. Secondly, self adaptive fusion is applied to the corresponded high or low frequency images by dynamic weighting of the extracted features. Thirdly, the final result image is generated based on coherence comparison of its high and frequency images obtained before. By fusion experiments of SAR and TM images, it appears that the proposed method has apparent advantage in reservation of information and boundary as well as neighboring coherence. |
