利用小波-Contourlet变换良好的多尺度性和多方向性特征,提出一种基于小波-Contourlet变换的多聚焦图像融合算法,引入Cycle Spinning来有效地消除由于小波.Contourlet变换缺乏平移不变性而产生的图像失真.实验结果表明,与其他基于多分辨率分析的多聚焦图像融合算法相比,该算法显著减小了融合图像的RMSE值,提高了融合图像的视觉效果.
An algorithm for multi-focus image fusion using wavelet based contourlet transform was proposed for the transform is of multi-scale and multi-direction,and cycle spinning was introduced to decrease the shift-variance of the transform.The resuits show that this algorithm improves the visual effect of the fused image and decreases the RMSE value.
