How to Set Up OpenCV 2.4.3 with Visual C 2010 Express?

Setting Up OpenCV 2.4.3 with Visual C 2010 Express

Installing OpenCV 2.4.3 in Visual C 2010 Express offers several benefits for computer vision development. Here's how to achieve this setup:

1. Installation

• Download OpenCV 2.4.3 from sourceforge.net.
• Install it in a convenient directory (e.g., C:).
• Add "C:opencvbuildx86vc10bin" to your system PATH for OpenCV DLL access.

2. Configuring Visual C

• Create an empty project and open the project properties.
• Under "VC Directories," add the OpenCV include directory: "C:opencvbuildinclude."
• Under "Library Directories," add the OpenCV library directory: "C:opencvbuildx86vc10lib."

• Under "Linker - Input," add the following additional dependencies (debug version):

  • opencv_calib3d243d.lib
  • opencv_contrib243d.lib
  • ...
  • (See question answer for full list)

3. Writing Your First OpenCV Program

• Create a new C file and include the OpenCV headers:

  • include

• Load an image and display it in a window:

  • Mat im = imread("c:/full/path/to/lena.jpg");
  • imshow("Image", im);
  • waitKey(0);
• Compile and run the program to see the loaded image.

4. Exploring Further

• Explore OpenCV samples in the directory "c:opencvsamplescpp" for inspiration.
• Utilize the OpenCV documentation and community resources for more in-depth learning.

By following these steps, you can effectively configure OpenCV 2.4.3 in Visual C 2010 Express, enabling you to develop powerful computer vision applications.
