You can use my new Android app to use the cameras on your phone for a live Fourier Transformation of objects and surroundings. It’s called Fourier Camera and it can be downloaded from the following link:

This application uses OpenCV and Qt framework. If you’ve got any questions about it, you can post your comments below.



How to Get Current App Version in Qt

I have tried numerous methods to get an application’s own version number and believe me this is the best way to get it. First of all if we consider the fact that setting a Qt application version is done in PRO file (qmake) using the following simple command:

VERSION = 1.2.3.4

Then getting this same value should be the easiest possible method.

Just add the following line to your PRO file after defining version as seen above and you can use the same version string wherever you like in the code:

DEFINES += APP_VERSION=\\\"$$VERSION\\\"

APP_VERSION will contain the string “1.2.3.4” and can be used in the C++ code.
