### Installing & Configuring with Visual Studio ###

In this tutorial, I am using OpenCV 2.4.5 and Visual Studio 2012. But it is almost same for other versions of OpenCV and Visual Studio.  
  
If you want, you can refer to the older post [Installing & Configuring OpenCV2.1 with Visual Studio 2010][Installing _ Configuring OpenCV2.1 with Visual Studio 2010].  
  
There are 2 ways to install OpenCV into your computer. But for a beginner, the most suitable way is the installation by using the pre-built libraries. So, I am going to discuss how to install OpenCV by using pre-built libraries.  
  
First of all you should have a suitable IDE. I installed [Visual Studio Express 2012][] which is a free edition. (You will need to register by giving your email address to obtain the free product key).  
  
Then you have to download OpenCV from [here][]. You can choose whatever version, you want. I choose OpenCV 2.4.5.  
  
Then double click the downloaded 'OpenCV-2.4.5.exe' file and it will be extracted to whatever location, you give. I gave C:\\ as the extracting location.  
  
Then you will need to set up environment variables correctly to be able to use OpenCV.  
  
  
**Steps to Set up Environmental Variable  
设置环境变量**

*  先看自己的电脑是64位还是32位
 *  Right click on '**My Computer**' and click '**Properties**' in the drop down menu. You will see a window like this.

<table style=""> 
 <tbody> 
  <tr> 
   <td><a href="http://1.bp.blogspot.com/-bZ_wA7_GpCE/UZ3jzoArGeI/AAAAAAAAASM/WRCQYo-ek6k/s1600/System+Architecture.png" style="text-decoration:none; color:rgb(136,136,136); margin-left:auto; margin-right:auto" rel="nofollow"><img alt="Find Bitness of a Computer" height="340" src="http://1.bp.blogspot.com/-bZ_wA7_GpCE/UZ3jzoArGeI/AAAAAAAAASM/WRCQYo-ek6k/s640/System+Architecture.png" title="Find Bitness of a Computer" width="640" style=""></a></td> 
  </tr> 
  <tr> 
   <td style="font-size:11px">Find Bitness of a Computer</td> 
  </tr> 
 </tbody> 
</table>

Here the System type is **32 bit** operating system. So the system architecture is x86.  
If the system type is **64 bit** operating system, the system architecture is x64.  
  
Both Visual Studio 2012 and OpenCV2.4.5 supports vc11. So, in this tutorial, I am going to use vc11 as the compiler type. You can find supporting compiler types of OpenCV, if you go to C:\\opencv\\build\\x86 or C:\\opencv\\build\\x64 according to your system architecture.  
  
Remember your **system architecture** and expected **compiler type** because you will need this in the middle part of this post.

*  Now you are ready to set the environment variables. This can be done in the command line or by using GUI. I am going to explain the GUI method.
    
     *  Right click on '**My Computer**' and click '**Properties**' in the drop down menu. You will see a window like this.

[![Advance System Settings][]][Advance System Settings 1]

*  Click '**Advance System Settings'** in the above window

*  Then click **'Environment Variables'**

[![Environment Variables][]][Environment Variables 1]

*  Then click **'New'** button at the bottom of the window

[![New Environment Variable][]][New Environment Variable 1]

*  Type OPENCV\_DIRagainst **Variable name:**. And type the location **C:\\opencv\\build\\**against the **Variable value:.**

[![Creating New Environment Variables][]][Creating New Environment Variables 1]

*  Then press **OK**

Now you have added a new environment variable to the system.

Now you are going to edit a system variable.

*  click **'Path' or 'PATH'** inside the list of System variables and thenclick **'Edit'** button at the bottom of the window

[![Edit Environment Variable][]][Edit Environment Variable 1]

*  Then add a ; to the end of the line and add the following%OPENCV\_DIR%\\x86\\vc11\\bin  after the semicolon. x86 is your system architecture and vc11 is the compiler type. How to find your system architecture and compiler type is explained at the beginning of the post. (Don't delete anything. Just append it at the end of the line.)

Hooray!! You have completed the installation of OpenCV. Next thing you have to do is configuring Visual Studio.

**Configure Visual Studio Express**

*  **Start Microsoft Visual Studio**
 *  **Go to File>New Project...**
 *  **Do everything as shown in the below image and click OK and then click Finish.**

[![Creating new Visual Studio Project][]][Creating new Visual Studio Project 1]

*  Press '**Ctrl**' key and then '**W**' while holding the 'Ctrl' key in your keyboard. Release both keys. Then press '**S'** in your keyboard. Then you will see the '**Solution Explorer**' pane in your right or left side of the Visual Studio window. In my case, it is in the right side.

[![Solution Explorer][]][Solution Explorer 1]

*  Then right click on the project name (you have entered this name in a previous step) and then click '**Properties**'

[![Solution Properties][]][Solution Properties 1]

*  Choose 'All Configurations' as indicated in the 1st box. Click the 3 places as pointed by next 3 boxes in the given order. Then copy and paste $(OPENCV\_DIR)\\include against the 'Additional Include Directories'

[![Adding Include Directories][]][Adding Include Directories 1]

*  Click the first 2 places as pointed by first 2 boxes in the given order.Then copy and paste $(OPENCV\_DIR)\\x86\\vc11\\lib against the 'Additional Library Directories'

[![Additional Library Directories][]][Additional Library Directories 1]

*  Click as illustrated below

[![Additional Dependencies][]][Additional Dependencies 1]

*  After you click the <Edit...> (4th arrow in the above image), dialog box will appear and you have to copy and paste following library file names. If you are using a different version of OpenCV other than 2.4.5, please check the 'C:\\opencv\\build\\x86\\vc11\\lib' location for respective file names.

opencv\_calib3d245d.lib

opencv\_contrib245d.lib

opencv\_core245d.lib

opencv\_features2d245d.lib

opencv\_flann245d.lib

opencv\_gpu245d.lib

opencv\_haartraining\_engined.lib

opencv\_highgui245d.lib

opencv\_imgproc245d.lib

opencv\_legacy245d.lib

opencv\_ml245d.lib

opencv\_nonfree245d.lib

opencv\_objdetect245d.lib

opencv\_photo245d.lib

opencv\_stitching245d.lib

opencv\_superres245d.lib

opencv\_ts245d.lib

opencv\_video245d.lib

opencv\_videostab245d.lib

These are some of the file names, you can find in the 'C:\\opencv\\build\\x86\\vc11' location.

Now click OK

Congratulations!! You have done with all of the configurations of your IDE. Now you are ready to write your first OpenCV application.
