That library is no longer maintained. I would suggest you to try the javacvPro library which is based on the latest version of OpenCV (2.3.1). Andres has mentioned and appreciated this library on his blog too. As for setting up OpenCV 2.3.1, if you're running Windows, check out my blog. I've written a tutorial on setting up OpenCV 2.3.1. You need to follow it till step 2. No need to download and install VC++.

Thank you very much for your answer, but there still seem to be some problems.

I tried to run some examples, but Processing stops at the very first line of the code which tries to create a variable like "opencv = new OpenCV(this);" and it says UnsetisfiedLinkError..

Does that mean that I did something wrong with seting opencv up? I mean, I downloaded and extracted the superpack.exe and a opencv folder was made. I renamed it, as you mentioned in your tutorial, to OpenCV 2.3.1 and ran your helper program to set the environment variables, but it still won't work..

I downloaded the javacPro library from this page, under "The latest version of the library is available here: javacvPro-0.3 (November 2011) "

Okay, so the necessary dll files required to run OpenCV are not getting linked.

When using the OpenCV helper, did you select 32-bit or 64? If you selected 64-bit, edit the user environment variable (Path) back to  %OPENCV% \build\ x86\ vc10 \bin  . Similarly edit LIB and INCLUDE and change x64 to x86.Unequal bit-ness is known to cause issues.  

Edit your system environment variable called Path. Append the location of OpenCV's bin folder to it. It must be having some values already, add a semicolon and then the bin folder's path.

Sorry for not answering for a week now, I was out of the country and didn't have much time for forums etc..

I'm really not sure what can I do anymore, I've done everything you said, but I still get the same error. Can you please just show me the values of your system variables and then I'll figure out how to change them?

Also, my OpenCV 2.3.1 directory doesn't have a opencv subdirectory and I have a x86 subdirectory in my build direcotry (which you don't have) so my path for the Path looks like:
C:\ OpenCV 2.3.1\ build\ x86\ vc10\ bin
instead of
C:\ OpenCV-2.3.1\ opencv\ build\ vc10\ bin

I'd really like to understand what exactly does this linking and setting varibales do and then maybe I'll figure out what am I doing wrong..

BTW, what's the difference between the User variables for User and System variables?

I figured it out. I tried installing it on a completely new Windows 7  system. Turns out you need to add the Intel Threaded Build Blocks related dlls as well. Download the latest version of TBB from here. This contains some important dll files needed by javacvPro. 

Extract the zip and copy all .dll files inside / bin / ia32 / vc10 and all .dll files in   / bin / ia32 / vc10 / irml into your  C:\ OpenCV 2.3.1\ build\ x86\ vc10\ bin

Restart processing and all javacvPro examples work like a charm! Here's a screenshot of my OpenCVs bin folder(extra dlls added from tbb):

That did the trick, it works!

Thank You so much for your time and answers, You saved me so much time of finding the ultimate solution!

Glad to have helped. :)

Just to make it clear, for others facing trouble installing OpenCV and Javacv Pro on Windows, the steps are:

1. Head over to this page, follow the instructions to setup opencv 2.3.1 till Step 2. (Use 32-bit mode)
2. Download the latest version of TBB for Windows from here.
3. Extract the TBB zip file and copy all .dll files inside / bin / ia32 / vc10 and all .dll files in   / bin / ia32 / vc10 / irml into your  C:\ OpenCV 2.3.1\ build\ x86\ vc10\ bin

Restart processing and all javacvPro examples work like a charm! Here's a screenshot of the OpenCVs bin folder(extra dlls added from tbb):

Congrats, it worked like charm for me too!

I was stuck with running the OpenCV examples on Processing...thanks a ton for the replies! 

Manindra - great work on this! I was about to give up on getting opencv and processing running when I stumbled upon your reply. I owe you. 

Hi,

Bree,

Thanks for the super quick reply; I was worried this topic had fallen into the abyss when I posted to it :D 

What is the value of your "path" environment variable?

To see your environment variables, hit Start, type "environment variables", and open user environment variables settings. 

I wrote a step-by-step guide for windows and opencv 2.3.1 with JavaCvPro. 

This is what happened when I followed the instructions...not sure which one is the correct value (sorry!!!)

HOLD THE PRESSES!

Hi guys,
Thanks for the thread!
I don't get it: I've been following it very meticulously and tried many many different things but I can't get it to work! :(

I'm using:

• processing 2.03b
• javacvPro-0.5
• jdk-7u7-windows-x64
• OpenCV-2.4.2
• tbb40_20120201oss_win

I moved the dll from TBB from the intel64/VC10 to the x64/VC10/bin of openCV
then I used the OpenCV_Helper using the 64bit option

When I launch any javacvpro example I got the error as if something was missing:

I don't really know where to look now! Maybe I should use earlier versions of those libraries?
Thanks in advance guys

The version required of processing is: 1.5.1 

Nice one, thank you!

Well it didn't work when I just switched back to processing 1.5.1 but then I switched back to opencv 2.3.1 and that made the trick!
Team awesome: thank you!

Hi all,

I can confirm now that it only works with OpenCV 2.3.1 and not 2.4.2

To double the above reply...its true that javaCVPro doesn't seems to worked with OpenCV 2.4.2 however it's working with OpenCV 2.3.1

I've tried nearly anything and I can't get this to work.

Hi Manindra,

I've a windows7 ultimate 32 bit OS

I earlier forgot to mention:

hey guys,

hey guys,
