推荐答案

这里有点晚了，但你应该看看 OpenCV 。

A bit late here, but you should check out OpenCV.

它可以编译为iPhone的静态库，可以将视频（逐帧）转换为灰度或两种颜色。

It can be compiled as a static lib for the iPhone and can convert video (frame by frame) to grayscale or two color.

你可以开始这里。还有其他资源可以解决此问题。

You can start here. There are other resources for doing this floating around.
