Image Processing & Computer Vision with OpenCV
OpenCV 2.0 Installation on Windows XP and Visual Studio 2008
Many of us thought of doing project in computer vision using OpenCV library. But beginners find it difficult to use the OpenCV library because of the installation problem. So here is quick tutorial to install OpenCV 2.0. This tutorial assumes that you use windows XP and Visual Studio 2008 Express Edition. Send your questions and feedback to shrinivas [at] iitg.ernet.in

There are some slight typos in the pdf that any reader should take notice of:
on page 5 it says
C:/OpenCV2.0/vs2008/debug
C:/OpenCV2.0/vs2008/Release
when it refers to the dll directories where it is supposed to say
C:/OpenCV2.0/vs2008/lib/debug
C:/OpenCV2.0/vs2008/lib/Release
respectively.

Hello, i followed your tutorial and i installed opencv with visual studio 2008, but when i debug and run the program it says highgui200.dll not found. This only happens when i have to include the highgui.h header file.
Any ideas?
PS: i get no errors at building process.
Thanks.

Cosmin,
check in the properties of the project (linker option) is set perfectly,(19th step) (not .dll but .lib)
if it is perfect, then check the as explained at step 13. if in this step if you cannot see the highgui200.lib then goto cmake process.

Joseph on Feb 1, 2010:
Hi,
Thank you for the instructions, they are very helpful. I had the same problem as Cosmin. I can build several projects just fine, and when I take out the commands from highgui200, it works fine. If I use the highgui200 commands, it will build and says no errors, but when I run the program it gives a message highgui200.dll not found.
I double checked that the folders were all generated correctly and it looks just like the document described. And the linker is the same too. And I set the paths correctly. I even tried dropping a copy of the dll in my working directory, and it gives the same message.
I am using windows 7 x32, I dont know if this is something pertaining to the operating system.

hi all thank you very much for this paper. i have the same problem with Joseph & Cosmin but i solve it by make a copy of these files: cv200.dll, cvaux200.dll, cxcore200.dll, cxts200.dll, highgui200.dll, ml200.dll and opencv_ffmpeg200.dll from E:\OpenCV2.0\xyz\bin\Release to Debug directory of the project and everything's ok.

Thanks yaar, it was a great help. I was dying since the last few days to get it working. The VS2008 integration problem even forced me to migrate to linux (was hassle free).
There is still a small mistake:
PATH should be
C:/OpenCV2.0/vs2008/bin/Debug
C:/OpenCV2.0/vs2008/bin/Release
instead of
C:/OpenCV2.0/vs2008/lib/Debug

I have been using the above PDF to install OpenCV. Thankyou very much - I found it incredibly useful.
Unfortunately the last instruction 22 is unclear.
21. Then open command prompt by Start->Run->cmd,
22. Change dir to the project debug folder and execute the .exe file by giving the image file
as the argument ( make sure that the file is in debug folder for simplicity )
What am I meant to type in the command prompt here? I know "cd" changes the directory.
But where is the debug folder?
And how do I give the image file as the argument? (Does that mean typing the name of the image file before or after)
What is the image file I am looking for? Is that "imageload.cpp", or is it some *.img file?
Sorry to bother you, but could you please help me here?

'cd' to where imageload.exe is located, and run it like this:
imageload.exe C:\photos\myphoto.jpg Lucas on Mar 5, 2010:
I followed SiddeeqHssn explanation but didn't solve it. It would still ask me for the same library but with a 'd' at the end. (example: 'cxcore200d.dll' instead of 'cxcore200.dll'). I just made a copy of the 'cxcore200' file, changed its name (added a 'd') and also pasted it in the Debug folder of the project. Not an elegant solution but it solved the problem.

Hi everyone,
Just wanted to throw out a huge thanks to the author, this saved me and got me running in OpenCV after a couple frustrating days. It's ridiculous that there is no document like this on the Open CV wiki. Have you thought about posting it there or on Willow Garage?
Anyway, I am using Windows 7 64 bit with VS2008 Pro, and OpenCV 2.0. I followed the PDF guide precisely, then ran into the missing highgui200.dll run-time error.
I fixed this by adding the following items to the System Path (not the user path), as per the suggestions of several other commentors:
C:\OpenCV2.0\vs2008\bin\Debug;
C:\OpenCV2.0\vs2008\bin\Release;
Thanks again.

I also experienced the missing dll files but solved it by replacing ...lib... with ...bin... in the Path (as sugg by other commenters) no need to copy the files to the project folder anymore.

Hi,
I have used Microsoft Visual C++ 2008 and OpenCV 2.0.
To install OpenCV 2.0 I have used the procedure described in
file OpenCV_2_0_Installation.pdf.
When I run my simple program which uses cvExtractSURF function,
next error appears:
Unhandled exception at 0x10010bf6 (cv200.dll) in ExtractSURF_2_0.exe:
0xC000001D: Illegal Instruction.
and points to the cvRound function.
The same program runs without problem when I used OpenCV 2.1.
Can somebody help me with this problem?
Thank you very much in advance,
Eduard

1) I'm curious: If I download and install OpenCV-2.0.0a-win32.exe, then why do I need to "Make" the software. All the include files, DLL, include files, and source files are already there. All I have to do is tell VS2008 where to find them.
2) Also, when I create an project and build it, I have to supply two sets of information to VS2008, one for Debug and one for release builds. I don't need to include the full list of lies and folders in both property sets, do I?

Hi there Shirinivas!
Great tutorial, found it very useful and simple. Really helped a lot.
For the ones that are still having problems with the higui200.dll question, here's the solution:
1. Go to Mycomputer->properties->Advanced-> Environment variable-
>PATH->edit (care, not user variables), and change "C:/OpenCV2.0/vs2008/lib/Debug; C:/OpenCV2.0/vs2008/lib/Release" for "C:/OpenCV2.0/vs2008/bin/Debug; C:/OpenCV2.0/vs2008/bin/Release"
2. Copy the .dll files found on C:\OpenCV2.0\vs2008\bin (both release and debug) to C:\Windows\System32 (for 32 bit OS) or C:\Windows\sysWOW64 (for 64-bitOS).
Thank you!

For the ones that are still having problems with the higui200.dll question, here's the solution:
1. Go to Mycomputer->properties->Advanced-> Environment variable-
>PATH->edit (care, not user variables), and change "C:/OpenCV2.0/vs2008/lib/Debug; C:/OpenCV2.0/vs2008/lib/Release" for "C:/OpenCV2.0/vs2008/bin/Debug; C:/OpenCV2.0/vs2008/bin/Release"
2. Copy the .dll files found on C:\OpenCV2.0\vs2008\bin (both release and debug) to C:\Windows\System32 (for 32 bit OS) or C:\Windows\sysWOW64 (for 64-bitOS).
Thank you!

I have recently been applying the OpenCV and cvBlobsLib libraries to a problem encountered in bioscience industry - that of creating images of sample spots printed on microarray slides. It has greatly improved our quality control processes in that it can reliably be used to extract an image taken from a Flea2 digital camera, using the FlyCapture SDK, and then uses OpenCV to convert to greyscale and then black and white (binary) and finally use cvBlobsLib to detect the presence/absence of microarray spots.
Previously this was very labour intensive, with slides having to be examined individually under the microscope or using GenePix scanning software etc.
Some results and tips on setting up OpenCV and cvBlobsLib on my blog:

I ended up using MinGW and Eclipse CTD instead however (which was even more complicated to get working, since it will only build using GCC 4.4.0, not 3.x.x or 4.4.1..)
Awesome site! I am just starting my final year project now, which is a robotics/machine vision/control theory project that will use OpenCV in part. Your tutorials and guides have made it a lot easier to get started with the library!
And it is terribly inspiring, now i've got tons of crazy projects I feel like doing involving webcams and image processing.
