| 摘 要： | 提出基于对偶树复小波变换的像素级多分辨分析图像融合算法．对多聚焦图像和遥感影像的实验结果表明，本方法较基于离散小波变换和传统IHS变换的融合方法，保留了更多的光谱信息，而且提高了融合图像的空间细节信息．

| Abstract: | This paper introduces a new method based on the dual-tree complex wavelet transform which represents the edges better than discrete wavelet transform.The experiment results of multifocus image and remote sensing image show that the proposed method is better than wavelet and IHS transform methods.It preserves more spectral information and spatial details. |
