How do I build it?

First you need (for Windows) :

1. Qt 5.X
2. OpenCV 3.X
3. (Optional) Visual Studio
4. Git

Set the following environmental variables

OPENCV_DIR (on my system its C:\source\libs\OpenCV\opencv-3.1\opencv\build\x64\vc12)

QTDIR (on my sustem its C:\Qt\5.7\msvc2013_64)

Open a shell according to your setup. I use Qt 5.7 64-bit for Desktop (MSVC 2013)

Go to /scripts run setEnv.cmd

go to /source run qmake -r make

(if you have Visual Studio) : run qmake -r -tp vc cmake

You can open the project in Visual Studio now go to /scripts run vcstart.cmd browse to your sln file and open it Click 'play'.. and play ;)

The program is pretty simple. It can be used as a starting point for your image processing application. And it can be used to explore some of the possibilities within OpenCV.

1. Import an image.
2. Right-click to open the processing menu
3. Add the filters you want to explore. You can stack them.
4. You can go to 'RGB' or 'HSV' to edit the channels separately
5. You can do some histogram processing
6. You can merge the channels into 1 image again
