中文说明：基于小波变换的图像融合源代码，小波变换的固有特性使其在图像处理中有如下优点：完善的重构能力，保证信号在分解过程中没有信息损失和冗余信息；把图像分解成平均图像和细节图像的组合，分别代表了图像的不同结构，因此容易提取原始图像的结构信息和细节信息；小波分析提供了与人类视觉系统方向相吻合的选择性图像。
English Description：
Image fusion source code based on wavelet transform, the inherent characteristics of wavelet transform in image processing has the following advantages: perfect reconstruction ability, to ensure that there is no information loss and redundant information in the signal decomposition process; the image is decomposed into the combination of average image and detail image, which represent the different structure of the image respectively, so it is easy to extract the structure and information of the original image Wavelet analysis provides a selective image which is consistent with the direction of human visual system.
