Building OpenCV with OpenGL support for iOS

Question

I'm currently developing some computer-vision application for blind people. Now we decided to move our studies on mobile apps.

Since OpenCV 2.4, building them for iOS is quite simple due to the two scripts.

The most problem I'm facing is time of processing. I read that most of image processing on iPhone is done with OpenGL. So I was wondering if could be a possibility to build OpenCV with OpenGL support when builded for iOS.

The processing time for very simple operation in OpenCV (on iPhone) is too long for real-time apps, especially if dedicated to blind people who need a rapid feed-back of reality.

Could someone help me?

Answer 1

It is not possible to build OpenCV with OpenGL support for iOS (and OS X). It is unconditionally disabled by the OpenCV's build scripts.

Actually OpenGl is not used in OpenCV for acceleration. So you will not get any speedup even after editing the sources.
