Mastering OpenCV with Practical Computer Vision Projects

Porting from desktop to Android

Now that the program works on the desktop, we can make an Android or iOS app from it. The details given here are specific to Android, but also apply when porting to iOS for Apple iPhone and iPad or similar devices. When developing Android apps, OpenCV can be used directly from Java, but the result is unlikely to be as efficient as native C/C++ code and doesn't allow the running of the same code on the desktop as it does for your mobile. So it is recommended to use C/C++ for most OpenCV+Android app development (readers who want to write OpenCV apps purely in Java can use the JavaCV library by Samuel Audet, available at http://code.google.com/p/javacv/, to run the same code on the desktop that we run on Android). ...
