拍摄多张照片并将其编辑成视频
您可以自动拍摄多张照片，然后为 iPhone 应用程序实时编辑它们吗？就像你想制作一个男人的视频并给他添加胡子一样，你可以在直播时做到这一点吗？小胡子根据检测到他的脸的位置移动，并说每秒大约 5-15 帧？
Can you auto take multiple pictures and then edit them in real time for an iphone app? Like say u want to make a video of a man and add a beard to him can you do it while streaming? the mustach moves according to where his face is detected and say take about 5-15 frames per second?

我想你可以。
至少会涉及跟踪一些面部特征或为此目的添加的标记。然而，这是一个如此广阔和复杂的领域，你很难在这里得到任何可以帮助你前进的建议。
如果你真的这么想，我建议你寻找增强现实库，那里有一些。它们中的大多数都是通过跟踪特殊模式而不是任意特征来工作的，因此请为大量工作负载做好准备。

I guess you can.
It would involve tracking some facial features or markers added for the purpose at the least. However this is such a vast and complex field, you'll hardly get a single advice here that will get you going.
If you really mean it, I'd suggest looking for Augmented Reality libraries, there's a few out there. Most of them work by tracking a special pattern and not arbitrary features though, so be prepared for a big load of work.
