Installation

Windows 8.1 system, visual studio 2013

• 1. Dowload opencv-2.4.11.exe

  2. Extract it to C:\local

  3. Set the system environmental variable OPENCV_DIR C:\local\opencv\build\x86\vc12 (I set the compiler of the installed VS 2013 32 bit, i.e. the target machine is 32 bit, therefore I chose "x86" instead of "x64". Despite the fact that the computer OS is 64 bit.)

  4. Update system environmental variable Path by adding %OPENCV_DIR%\bin

Test

1. Generate a new empty c++ console project

2. Properties of the project (under release mode)

4. Test the following codes under both debug and release modes

#include <cstdio>

#include<opencv2\opencv.hpp>

void main()

{

std::cout << "OpenCV Version: " << CV_VERSION << std::endl;

}

More Test

#include "opencv2/core/core.hpp"

#include "opencv2/highgui/highgui.hpp"

using namespace cv;

using namespace std;

int main()

{

Mat img;

img = imread("Kitten1280x800.jpg", CV_LOAD_IMAGE_COLOR);

namedWindow("A kitten!", WINDOW_AUTOSIZE);

imshow("A kitten!", img);

waitKey(10000);
