阐述了基于拉普拉斯金字塔图像融合的原理和方法,首先对原图像分别进行拉普拉斯金字塔分解,接着在对应的分层子图像上采用变换区域特征量测法进行融合,然后对得到的拉普拉斯金字塔反变换得到融合图像。通过使用MATLAB软件对本文研究的融合算法进行仿真实验,实验结果证明基于拉普拉斯金字塔图像融合方法得到的融合图像视觉效果良好,可视化清晰,图像质量得到了较大提高,该技术可广泛应用于多种研究领域。

The method image fusion based on Laplacian pyramid is an important way for Multi-focus image fusion . this paper introduce the principle of Laplacian pyramid transform and based on it the fusion strategy in detail. The method mainly composed of three steps. Firstly, the Laplacian pyramids of each source image are deconstructed separately, and then each level of new Laplacian pyramid is fused by adopting different fusion rules. To the top level, it adopts the maximum region information rule;and to the rest levels, it adopts the maximum region energy rule. Finally, the fused image is obtained by inverse Laplacian pyramid transform. Two sets of images are applied to verify the fusion approach proposed and compared it with other fusion approaches. By analyzing the ex-perimental results, it showed that this method has good performance, and the quality of the fused image is better than the results of other methods.
