How to Configure OpenCV-2.3 with Visual Studio 2010?

Configuring OpenCV-2.3 for Visual Studio 2010

While the official guide focuses on installing OpenCV-2.1, this article provides comprehensive instructions for properly setting up OpenCV-2.3 (x86 version) in Visual Studio 2010 (Express).

Setup Steps:

1. Extract OpenCV Library: Download and extract OpenCV-2.3.0-win-superpack.exe to your desired location, such as C:OpenCV2.3.
2. Create Visual Studio Project: Start a new Win32 Console Application project in Visual Studio. Choose "Empty Project" in the Application Settings.
3. Add Sample Code: Create a main.cpp file and insert the sample code provided below:

#include <stdio.h>
#include <cv.h>
#include <highgui.h>

int main(int argc, char* argv[]) {
    if (argc \n");
        return -1;
    }

    IplImage* img = cvLoadImage(argv[1], CV_LOAD_IMAGE_UNCHANGED);
    if (!img) {
        return -1;
    }

    cvNamedWindow("display", CV_WINDOW_AUTOSIZE);
    cvShowImage("display", img);

    cvWaitKey(0);

    return 0;
}</highgui.h></cv.h></stdio.h>

4. Configure Include Directories: In Project Properties > C/C > General, add these paths to Additional Include Directories:

   • C:OpenCV2.3buildincludeopencv
   • C:OpenCV2.3buildincludeopencv2
   • C:OpenCV2.3buildinclude

5. Configure Library Directories: In Project Properties > Linker > General, add this path to Additional Library Directories:

   • C:OpenCV2.3buildx86vc9lib

6. Link OpenCV Libraries: In Project Properties > Linker > Input, add the following libraries:

   • opencv_core230.lib
   • opencv_highgui230.lib

7. Set PATH Environment Variable: Append the following path to your PATH environment variable:

   • ; C:OpenCV2.3buildx86vc9bin

Execution:

Press F7 to build the solution. Ensure it succeeds without errors. To execute the application, make sure the PATH modification is applied and you can run OpenCV commands directly from the command prompt.
