摘　　要：提出一种新的基于小波变换与LBP算子相结合的遥感图像融合算法.该算法在源图像小波变换的高频子带内,利用局部LBP算子极大的方法得到小波重构高频系数,而低频系数则利用源图像小波分解后低频子带系数的非线性加权得到.然后由此高频和低频系数进行小波重构得到融合图像.实验采用可见光图像与SAR图像融合,结果表明这种方法可以很好地在保留源图像各自信息的同时融合源图像的细节信息,并且能够有效抑制源图像中孤立噪声点.A novel wavelet and LBP operator based on remote sensing image fusion algorithm is proposed. The algorithm reconstructs the high frequency coefficients using local LBP operator maximization method. Then composite low frequency coefficients are merged by nonlinear weight on sources counterparts. Experiment results show that the proposed algorithm can merge the detail of sources while suppressing the speckle noises, which is conducted on optical and SAR images, and can effectively inhibit the source image to isolate noise points.
