最近发现了一个摩尔纹相关的研究方向—【图像加密/隐藏】
通过一张任意的moire图像和另一张图像叠加,实现图像隐藏,最早在04年被提出
目前整理了从如下的文献(还在增加),感觉可以用deep learning做一下

使用简单的纹理a对b加密,产生摩尔纹隐藏图像,f为解密
推广到复杂的图像纹理,以图像为图像加密
图a为待加密图像,从任意图像b中取出随机一部分图c作为随机摩尔栅格
D为加密后的图像,e为解密图像
现有的limitation
- 只能处理灰度图,是否可以推广到RGB图像
- 提高解密图像的PSNR(减少画面瑕疵),理论上e和a要尽可能相似,d和c要尽可能相似
解密过程感觉和demoire网络有很大的关联性
这些文献涉及的摩尔纹生成也对去摩尔纹的数学和物理原理有帮助
