Need examples of Augmented Reality on Android with OpenCV

edit

That sample is just changing the whole frame it's not augmented reality or am i missing something?

Without entering in a complex (and useless?) discussion on what is or what is not ''augmented reality'', I (personally) think that the alien face is augmented reality. Nevertheless, let us know what ''kind'' of augmented reality you want and we can provided some resources.

You are probably right of it being Augmented Reality. But i'm looking for a way to simulate/draw an object onto a surface that is pre-defined. As an example this picture: https://github.com/MasteringOpenCV/code/blob/master/Chapter3_MarkerlessAR/screenshot.png?raw=true

This code is easy to port to Android. The implementation is pure C++, and things you have to do are: 1) create a java canvas to see the results 2) use ORB/FAST instead of SIFT/SURF which are unfree and then slightly more complicated to exploit under Android plateform. 3) upload a picture of your object to track or create a java interface to take a picture and resize it to keep only the ''marker''.

Some of my students have do it recently, the performances aren't too bad, but the C++ OpenGL usage to display the cube isn't the best way in my opinion...

Enjoy and let us know!
