Install OpenCV in windows

Step-1 : Copy all the following files in D drive

• MinGW(folder)
• OpenCV
• cmake-2.8.12.2-win32-x86.exe

Step-2: Set Enviroment path of D:\OpenCV\MinGW\bin

Step-3: Run exe cmake-2.8.12.2-win32-x86.exe and give the source path of openCV

and destination path (Create a new folder in give the path of that folder)

Step-4: Click on configure button

Step-5: Click on generate button

Step-6: Open CMD prompt and go to the destination path  that configure at the time of  Run exe cmake-2.8.12.2-win32-x86.exe.

Step-7: now Type minGW32-make. press enter.

Step-8: Set enviroment variable path of generated bin folder. D:\OpenCV\OpenCV Build\bin.

Step-9: Install Eclipse and then open new C++ project.

Step-10: File->New->Project->C++ Project->(Next)->[Project Type]Helloworld C++ Project, [Toolchains] MinGW GCC and write project name–>(Finish)

Step-11: Click on created project folder in eclipse Project explorer window

and then go to Project Tab from Top menu–>Properties–>c/C++ Build-->Setting

Then Go To Tool Setting Tab –>GCC C++ Compilar –> Include –> Write the include folder path of OpenCV eg:D:\OpenCV\OpenCV\Windows\opencv\build\include –>MinGW C++ Linker –>Libraries –> Copy the name of all DLL Files from the build folder and paste in Linraries pane eg: D:\OpenCV\OpenCV_Build\lib–> and copy the path D:\OpenCV\OpenCV_Build\lib and paste in Library search path Pane–>Then Apply and OK

Step-12: Now run the Test Code
