根据实际应用中要求图像融合算法简单有效的要求，基于对可见光图像和红外图像特征的分析，提出了基于相位调制的图像融合算法。对可见光图像和红外图像按照通信原理中的相位调制方法进行相位调制，通过逆变换得到融合图像。实验结果表明，该算法在图像视觉效果、包含的信息量以及细节信息上都取得很好的效果，融合效果优于小波变换等算法。

The purpose of this paper is to find a practical and effective fusion method for infrared and visible images. On the basis of analyzing the characteristics of visible and infrared images, a novel method for fusion of the infrared and the visible images based on phase modulation is proposed. Phase modulation on the visible and infrared images is conducted. Then the fusion image through inverse transformation is obtained. Experimental results show that the method discussed above is effective in visual effect, the quantity of information, and the details of information. It also shows that this new method gets a better fusion image than wavelet transform.
