"This one is the simplest tutorial on How To Install OpenCV"


Know how to earn through Cloud computing without investing anything, without doing any work.

Shopping FREE of Cost :) (Without doing any work)

Requirements-

1. OpenCVmod_32bit
2. Visual Studio 2010 / 2012
3. Windows 7 / 8

(Thanks to Hongbo Miao for this tutorial to install OpenCV 2.4.4 for Visual Studio 2012.)

Follow the steps carefully. Don't miss a single step and you are ON.

Step-1

Extract the zip file and store it in "C" drive. Now it should look like "C:/OpenCV/install/" ( Inside install folder bin, include and lib folder should be there) (This tutorial follow this path "C:/OpenCV/install/".)

Open Windows Explorer. Click on Computer and then System properties.

Choose Advanced system settings.

Click Environment Variables...

Add only this to Environment Variables -> System variables -> Path

C:\OpenCV\install\bin

---

Step-2

Create a new project without any source file.

For Debug:

View -> Property Manager

1. C/C++ -> General -> Additional Include Directories

C:\OpenCV\install\include\opencv

C:\OpenCV\install\include

1. Linker -> General -> Additional Library Directories

C:\OpenCV\install\lib

1. Linker -> Input -> Additional Dependencies

Note the file names has extra "d" which means debug

                             and its over...

Now restart the system and run the below code for testing.

Sample code:

//Reading an image

#include "opencv2\core\core.hpp"
#include "opencv2\highgui\highgui.hpp"
#include "cv.h"
#include "highgui.h"

using namespace std;

using namespace cv;

void main()

{

Mat image = imread("00.jpg"); //Give the full path to the image file

namedWindow("mywin");

imshow("mywin", image);

waitKey(0);

}

Sample code:

//Playing Video

#include "cv.h" 

#include "opencv2\core\core.hpp"
#include "opencv2\highgui\highgui.hpp"

#include "highgui.h" 

using namespace cv;

int main() 

{ 

// Open the video file

VideoCapture capture("asmall.avi"); //Give the full path for the video file

// check if video successfully opened

if (!capture.isOpened())

return 1;

// Get the frame rate

bool stop(false);

Mat frame; // current video frame

namedWindow("Extracted Frame");

// Delay between each frame in ms

// corresponds to video frame rate

// for all frames in video

while (!stop) {

// read next frame if any 

if (!capture.read(frame))

break;

imshow("Extracted Frame",frame);

// introduce a delay in mili-second

waitKey(50);

}

// Close the video file.

// Not required since called by destructor

capture.release();

return 0; 

}
