| 摘 要： | 利用基于光流的运动估计对岩心图像配准后，针对岩心高低不平图像出现部分模糊现象，提出了一种基于Curvelet变换的多聚焦图像融合方法，先对不同聚焦图像进行Curvelet变换，采取低频分量取加权平均、高频分量取绝对值最大的融合规则，再进行Curvelet反变换。实验表明，基于Curvelet变换的融合方法可有效综合多聚焦图像，相比基于小波变换的图像融合，能获得更好的融合效果。

| Abstract: | After using the motion estimation based on optical flow to make the core image registration,and because of the fuzzy part of rugged core image,a new multi-focus image fusion method based on Curvelet transform is proposed.First,two different focus images are decomposed using Curvelet transform separately,then the new Curvelet coefficients are acquired by adopting a simple fusion rule,i.e.low -frequency coefficients uses the weighted average and high -frequency coefficients uses the largest absolute value.Fin... |
