基于IHS色彩空间和Contourlet变换的图像融合方法

Image Fusion Method Based on IHS Color Space and Contourlet Transform

提出了一种基于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地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。

A image fusion technology based on Contouriet transform and IHS color space are presented. The method first converts color images with IttS 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.
