基于拉普拉斯金字塔变换的图像融合算法研究

阐述了基于拉普拉斯金字塔变换的图像融合原理和方法：首先对源图像分别进行拉普拉斯金字塔分解，然后对分解后的各层图像采用不同的融合准则进行融合，最后，对融合金字塔做拉普拉斯金字塔反变换得到最终的融合图像。通过对可见光与红外图像的融合结果分析，实验结果表明，该算法能得到具有更多有用信息的高对比度的融合图像。融合效果良好。

Research on Image Fusion Algorithm Based on Laplacian Pyramid Transform

This paper explains the theory and method of image fusion based on Laplacian pyramid.The Laplacian image fusion scheme begins by constructing Laplacian pyramids for each source image,and then each level of Laplacian pyramids is fused with different fusion rule.Finally,the end fused image is obtained by inverse Laplacian pyramid transform.By analyzing the fusion image with visible and infrared image,the experimental results show that this algorithm can produce high-contrast fusion image that are clearly more appealing and have greater useful information content.It proves that the algorithm can get a good fusion result.
