OpenCV build for iPhone with example project

Computer vision with iOS: Building an OpenCV framework

This is the source code that accompanies our article on how to build an OpenCV framework for iOS devices. The framework can be added to your projects by dragging and dropping and supports video capture using the OpenCV highgui module.

13/02/12 - Updated for iOS 5, armv6 support dropped. OpenCV.framework updated to trunk r7286. Aziz Baibabaev (Abai)

Doesn't cater for retina images?

-CVMat and -CVGrayscaleMat need to be amended to take into account the UIImage::scale member. For example, with '@2x' images the scale is set to 2.0, but these CV*Mat methods will render such images at a lower resolution.
