由于成像方式及波谱接收段的不同.合成孔径雷达SAR(synthetic aperture radar)与可见光图像所反映的信息有很大差异,图像之间相关性弱,且互补性明显。因此在图像融合时,应该根据其互补性信息特征各取所长。在研究了一些现有融合方法的基础上,提出了一种基于互补信息特征的SAR与可见光图像融合方法。首先通过基于像素邻域的能量统计特性融合SAR与可见光图像,将SAR图像中的重要目标信息加入到可见光图像中,然后再利用小波变换进行二次融今,充分加入原始图像的边缘细节信息。实验结果表明,该融合方法有效。-err

ICA算法The algorithm is equivalent to Infomax by Bell and Sejnowski 1995 [1] using a maximum likelihood formulation. No noise is assumed and the number of observations must equal the number of sources. The BFGS method [2] is used for optimization. The number of independent components are calculated using Bayes Information Criterion [3] (BIC), with PCA for dimension reduction.-ICA algorithm:The algorithm is equivalent to Infomax by Bell and Sejnowski 1995 [1] using a maximum likelihood formulation.
