3. What is OpenCV ? OpenCV is a based on C / C + + language, open source image processing library Develop by Inter Free to use

4. What can OpenCV do ？ Image data manipulation Image and video I/O Matrix and vector manipulation and linear algebra routines Various dynamic data structures Basic image processing Structural Camera calibration Motion analysis Object recognition Basic GUI Image labeling

5. How to setup openCV ? Downlinks: 1. OpenCV lib http://sourceforge.net/projects/opencvlibrary/files/ http://sourceforge.net/projects/opencvlibrary/files/ 2.VS2008 http://www.microsoft.com/express/product/default.aspx http://www.microsoft.com/express/product/default.aspx 3.Codeblock http://www.codeblocks.org/ 4. Cmake http://www.cmake.org/cmake/resources/software.html

6. Download OpenCV and install Download the OpenCV 2.1.0 Windows installer from SourceForge - "OpenCV-2.1.0- win32-vs2008.exe". Download the OpenCV 2.1.0 Windows installer from SourceForge Install it to a folder (without any spaces in it), say "C:\OpenCV2.1\". This article will refer to this path as $openCVDir During installation, enable the option "Add OpenCV to the system PATH for all users".

7. Setup OpenCV in VS2008 1. Configure Visual Studio Open VC++ Directories configuration: Tools > Options > Projects and Solutions > VC++ Directories Choose "Show directories for: Include files" – Add "$openCVDir\include\opencv" Choose "Show directories for: Library files" – Add "$openCVDir\lib" Choose "Show directories for: Source files" – Add "$openCVDir\src\cv" – Add "$openCVDir\src\cvaux" – Add "$openCVDir\src\cxcore" – Add "$openCVDir\src\highgui"

8. Setup OpenCV in VS2008 2. Configure your Project After you've created a project you'll need to add the OpenCV dependencies. Open Project Properties: Project > %projectName% Properties... Open Linker Input properties: Configuration Properties > Linker > Input Open the "..." window to edit "Additional Dependencies" and on each line put: – "cv210.lib" – "cxcore210.lib" – "highgui210.lib" – And any other lib file necessary for your project Your project should now build. If you get any errors try restarting Visual Studio and then doing a clean Rebuild.

12. Setup openCV in codeblock 3.Write a test program

13. Setup openCV in codeblock Sample program #include "cv.h" #include "highgui.h" int main( int argc, char** argv ) { – IplImage* pImg; – if( argc == 2 && – (pImg = cvLoadImage( argv[1], 1)) != 0 ) { cvNamedWindow( "Image", 1 ); cvShowImage( "Image", pImg ); cvWaitKey(0); cvDestroyWindow( "Image" ); cvReleaseImage( &pImg ); return 0; – } – return -1; }
