摘要
基于非采样Contourlet变换,提出了一种新的图像融合算法.对经非采样Contourlet变换后的低频子带系数采取基于区域清晰度的融合规则,对高频子带系数采取基于区域方差的自适应加权的融合规则.实验结果显示,本文算法在目视判别以及客观标准下优于其他基于多尺度分析的图像融合算法,可获得较理想的融合图像.
A new image fusion algorithm is proposed based on the nonsubsampled contourlet transform （NSCT）. After the NSCT of image, the regional definition as the regular for the low frequency subband coefficients, and adaptive weight based on the regional variance as the regular for the high frequency subbands coefficients. The experimental results show that the presented algorithm improves the visual quality and objective indexes. This algorithm can obtain quite good fused image.
