How to Install OpenCV 2.4.3 in Visual C 2010 Express

To install OpenCV 2.4.3 in Visual C 2010 Express, follow these steps:

1. Installation

• Download the OpenCV 2.4.3 source file from SourceForge.net.
• Extract the contents to a designated directory.
• Add the directory C:opencvbuildx86vc10bin to your system PATH (via Control Panel → System → Advanced system settings → Advanced → Environment variables...).

2. Project Configuration

• Create a new empty project in Visual C with Debug configuration.
• In the project properties → VC Directories, add C:opencvbuildinclude to Include Directories and C:opencvbuildx86vc10lib to Library Directories.

• In the project properties → Linker → Input, add the following dependencies (with the "_d" suffix indicating the "Debug" configuration):

  opencv_calib3d243d.lib
  opencv_contrib243d.lib
  opencv_core243d.lib
  opencv_features2d243d.lib
  opencv_flann243d.lib
  opencv_gpu243d.lib
  opencv_haartraining_engined.lib
  opencv_highgui243d.lib
  opencv_imgproc243d.lib
  opencv_legacy243d.lib
  opencv_ml243d.lib
  opencv_nonfree243d.lib
  opencv_objdetect243d.lib
  opencv_photo243d.lib
  opencv_stitching243d.lib
  opencv_ts243d.lib
  opencv_video243d.lib
  opencv_videostab243d.lib

• For Release configuration (optional), replace the "_d" suffix with "_".

3. Code Example

• Create a new C file in your project and enter the following code:

  #include <opencv2/highgui/highgui.hpp>
  #include <iostream>
  
  using namespace cv;
  using namespace std;
  
  int main()
  {
    // Load and display an image
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
    return 0;
  }

• Compile the code (F5) and it should display an image in a window.
