基于IHS色彩空间和Contourlet变换的图像融合方法

本文提出一种基于Contourlet变换与IHS色彩空间的图像融合方法。该方法首先对彩色图像进行IHS空间转换，然后对待融合图像的I分量做融合规则融合即首先对I分量做Canny算子运算。在计算出图像的边缘点后，再对边缘点和非边缘点做不同规则的融合。该方法对彩色图像的处理能有效的提供图像的清晰度和相关系数。实验仿真结果表明：与加权融合、PCA融合方法比较，该方法能有效改善融合质量并取得较好的视觉融合效果。

Image fusion method based on HIS color space and Contourlet transform

A image fusion technology based on Contourlet transform and IHS color space are presented.The method first converts color images with IHS space,and then the I component of the fused image is fused in fusion rules,namely I component is first computed in Canny operator.After calculating the image edge points,these edge points and non-edge points are fused with different rules.The method can provide image clarity and correlation coefficient in color image’s processing.The experimental simulation results show that:the proposed method can enhance effectively quality of image fusion,and get better visual effects,which is compared to weighted fusion or PCA fusion.
