中文说明：变换域图像融合算法，将变换后的两个和多个图像进行融合，再通过反变换得到融合后的图像。这里介绍了基于小波变换的图像融合和基于拉普拉斯金字塔变换的图像融合。
English Description：
Transform-domain algorithm for image fusion, transformation and fusion of two or more images, and then by inverse transform to get fusion images. Here is image fusion based on wavelet transformation and image fusion based on Laplacian pyramid.
