摘　　要：利用Geert Uytterhoeven提出的一种非张量积小波(Red-Black小波)来进行图像融合。首先基于提升框架的思想构造Red-Black小波,然后将其应用于两组图像融合实验:不同聚焦点图像融合与可见光—红外图像融合;并分别采用基于统计特性和信息量的评价指标,将本文方法与db4张量积小波的图像融合方法进行了比较。实验结果表明,本文的方法优于db4张量积小波的图像融合方法。In this paper, image fusion method based on a sort of non -separable wavelet （Red - Black Wavelet） was proposed. Firstly, we constructed Red - Black Wavelet by Lifting Scheme. Secondly, we applied the Red - Black wavelet to two image fusion experiments ： fusion of multifocus images; fusion of CCD and IR images. Finally,we evaluated the method＇ s performance by some objective criteria based on statistics or informatics. The experimental results demonstrated higher performance of our presented method compared to the same algorithm using db4 separable wavelet.
