摘　　要：研究了基于小波变换的多分辨率图像融合的理论和方法,提出了一种以小波局部能量作为融合特征的融合算法,并讨论了融合图像的评价问题.实验表明:所提算法在熵、交叉熵、均方根误差和峰值信噪比等方面都有较好的效果.The paper has investigated the theory and methods of wavelet based multi-resolution image fusion, and proposed a novel algorithm of image fusion which chooses local wavelet energy as fusion feature. The issue regarding evaluation of fusion result is also discussed. Simulation experiments demonstrate that the presented image fusion method has offered better results with respect to entropy, cross entropy, root mean square error, as well as peak signal-to-noise ratio.
