绿屏/色度键iOS [英] Green screen / chroma key iOS

问题描述

我正试图在iOS上实时进行绿屏减法。我在我的项目中包含了openCV，我可以使用本教程从相机中获取原始数据： http://www.benjaminloulier.com/articles/ios4-and-direct-access-to-the-camera
然后我从CGImageRef转换为IplImage。
我坚持的是，使用openCV，我该如何进行绿屏减法？或者是否有一个更简单的图像库我可以用于iOS来实现这个目标？

I am trying to do green screen subtraction in real time on iOS. I have included openCV in my project and I can get the raw data from the camera using this tutorial: http://www.benjaminloulier.com/articles/ios4-and-direct-access-to-the-camera Then after I convert from CGImageRef to IplImage. What I am stuck at is, using openCV, how can I do this green screen subtraction? Or is there a simpler image library I can use for iOS to achieve this?

谢谢
