Stage I阶段1的目的是什么？

[Haolin0817]

Since the second stage is to directly use visible image and infrared image to extract features and fuse, what is the purpose of rebuilding the original infrared image and visible image generated at the end of the first stage? Please kindly help me with understanding friends to answer it, thank you very much!

既然二阶段是直接使用可见光图像和红外图像进行提取特征并融合，一阶段最后生成的重建原始红外图像和可见光图像的目的是什么呢，麻烦有理解的朋友帮我解答一下，万分感谢！
