看到模糊的照片，是不是有还原真实面目的冲动？以前的技术做不到，在AI时代一切皆有可能。美国杜克大学开发的AI算法就可以做到马赛克图片变高清。

低清变高清的算法并不稀奇，目前技术都支持了SDR超分辨率技术，包括视频画质增强、图片增强等领域都有这个算法的存在，它将低分辨率图片填补细节，给图片增加像素以尽可能提高画质。

　　美国杜克大学今年发明了一种新的AI算法，名为PULSE（Photo Upsampling via Latent Space Exploration），虽然也是SR超分辨率技术，但它不是填补像素，而是先生成高清大图，然后降低图片分辨率与原始图片对比，从中找到匹配程度最高的图像

　　PULSE算法可以在短短几秒内就把16×16像素的低分辨率图片提升到1024×1024级别，精度提升了64倍，而之前的AI算法提升不过8倍左右。

这个算法已经开源了，在Github上可以找到他们的代码，预计未来会有很多软件或者应用会集成这一算法。

以后再有马赛克照片，或许就可以靠它来还原真面目了。
