-OpenCV - Qt Integration
-=======================
-
-This code sample shows you how to do basic image manipulation to an image and display the result using the `QLabel` widget. The code loads `The_Chapter_House.jpg` from the `assets/` directory and provides two buttons to perform some basic manipulation.

-
-The same program written in Python is available in the `python/` directory.
-
-To compile and run the code, you need to have Qt 5 installed on your computer. The code is successfully tested on the following environment:
-
- - Mac OS X Mavericks
- - Qt 5.3.0
- - OpenCV 3.0.0
- - Python 3.4.1
-
-Compiling
----------
-
-Open `ImageApp.pro` and modify the variables to match with your system. For example, you might need to modify the paths for the includes and libraries especially if you're on Windows.
-
- INCLUDEPATH += /usr/local/include
- LIBS += -L/usr/local/lib -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_imgcodecs
-
-Change your working directory and compile the code by typing:
-
- qmake
- make
-
-If everything is ok, it will produce an executable: `ImageApp` (Linux), `ImageApp.exe` (Windows), or `ImageApp.app` (Mac). Run the executable and you will see the GUI like the screenshot above.
-
-Known Issues
-------------
-
-In `ImageApp.cpp`, the code using relative path to locate the input image:
-
- img = cv::imread("../assets/The_Chapter_House.jpg");
-
-If the program cannot display the image and shows the "Cannot load the input image!" warning, try to use absolute path instead. For example:
-
- img = cv::imread("/full/path/to/The_Chapter_House.jpg");
