Update: These instructions are also applicable for 2.4+ version of opencv and javacv.
I was looking for image processing library for Java. My search stopped at JavaCV. JavaCV provides wrappers for OpenCV. so you can directly use OpenCV functions in Java. JavaCV also provides hardware accelerated full screen Image display with CanvasFrame and GLCanvasFrame.
JavaCV provides jar files which can be used with OpenCV installation. Following steps can be followed to setup JavaCV with Eclipse on Windows 7.
For 64 bit: http://www.microsoft.com/download/en/details.aspx?id=14632
In System variable select path and click on Edit. Now add following address in Variable address. I have extracted opencv package in C:\ directory. If you have installed at different location please update address accordingly.
For OpenCV 2.4.2 and earlier version
For 32 bit:
C:\opencv\build\x86\vc10\bin;C:\opencv\build\common\tbb\ia32\vc10\
For 64 bit:
C:\opencv\build\x64\vc10\bin;C:\opencv\build\common\tbb\intel64\vc10\
For OpenCV 2.4.3 and later version
For 32 bit:
C:\opencv\build\x86\vc10\bin
For 64 bit:
C:\opencv\build\x64\vc10\bin
Once this is done, the most important step is to Restart Windows.
Result will look like this

JavaCV provides jar files which can be used with OpenCV installation. Following steps can be followed to setup JavaCV with Eclipse on Windows 7.
1.Install Java Development Kit (JDK) from the link below. Make sure to install 32bit or 64 bit as per your processor.
http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u32-downloads-1594644.html2. Install Microsoft Visual C++ redistributable package
For 32 bit: http://www.microsoft.com/download/en/details.aspx?id=5555For 64 bit: http://www.microsoft.com/download/en/details.aspx?id=14632
3. Download OpenCV super-pack from Sourceforge and extract it in you C:\Opencv
http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.3.1/4. Set OpenCV .dll in systems path so that JavaCV can access it.
Go to Control Panel > System Security > System > Advanced System Settings > Environment VariablesIn System variable select path and click on Edit. Now add following address in Variable address. I have extracted opencv package in C:\ directory. If you have installed at different location please update address accordingly.
For OpenCV 2.4.2 and earlier version

C:\opencv\build\x86\vc10\bin
For 64 bit:
C:\opencv\build\x64\vc10\bin
Once this is done, the most important step is to Restart Windows.
5. Download JavaCV- bin from link below and extract it.
http://code.google.com/p/javacv/downloads/list6. Create New Java Project 'demo' in Eclipse.
Once created, go to Project > Properties > Java Build Path > Libraries > Add External JARs .
Go to your JavaCV Extracted folder and add all jar files. It should look like the pic below
7. Now create demo.java in src folder of the project.
Paste following code and run the project.Put your image in project folder. In my case it is 'img1.png'Result will look like this
Do you have any idea why i get the following error when running your code?

DeleteI put "jpeg" picture, and used this file name in the code. then have the same error as u.
and I change "jpeg" to "jpg" in code. then without any problem and showed picture~~=]
It looks like your code is not able to locate image which is why it is showing null pointer exception. More specific reason can be identified by looking at code.
ReplyDeleteI get java.lang.UnsatisfiedLinkError C:\Users\..\AppData\Local\Temp\jniopencv_core4254130985403942592.dll Can't find dependent libraries exception when run the code.
ReplyDeleteI have JDK 64bit and Netbeans 7.2 on windows 7 64bit
i set the path to OpenCV as you mention in the blog post.
Make sure you are setting path to 64 bit opencv. Also javacv and opencv version should be same. Don't forget to restart system after setting path.
DeleteHi i even i m getting same error as above that is cant find dependent libraries. can you tell me the how should i identify OpenCV & JavaCV are 32/64 bits.plz help me my work is struc from 15days.
ReplyDelete'Can't Dependent libraries' issue mostly arises due to following reasons.
Delete1. javacv and opencv version are not compatible. i.e. you should use opencv 2.4.0 for javacv 0.2
Required opencv version can be found in readme file with javacv package.
2. One should link 32 bit opencv libs with 32 bit javacv and 64 bit opencv libs with 64 bit javacv. You should have 64 bit process in order to use 64 bit libs.
opencv comes with both 32 and 64 bit libs. You should link need libs are per explained in step 4 in above blog-post. You should worry about javacv if you are linking all the jar files provided by javacv package in step 6 in above blog-post.
3. Set the 'path' correctly as suggested in setp 4 in above blog-post. Don't forget to restart your system before using it.
I hope this should help. If you are still getting error after this, try posting full error log.
Thank you nikil its working...

I'm using the 64-bit versions of javacv v0.2 and opencv v2.4.2, with eclipse on Win7. Any guidance greatly appreciated - thanks!
This error is generated when your setup is not able to find opencv binaries. Are you able to run opencv alone on your system. I got javacv working by following all steps mentioned in above post. Try re-installing opencv and see if it works. Make sure your processor and operating system both are 64 bit. Otherwise you will have to use everything 32bit.
DeleteHi Nikhil,
ReplyDeleteMy processor is a i3-2310M and Win7 also reports 64 bits, so no problem there. I looked at eclipse but couldn't see anything that said 64 bits - I'm pretty sure that I installed the 64-bit version.
For the paths: I copied them out of the Environment Variables and pasted them into the URL of a folder: up popped the files. So I think that part is OK. Don't know what's left to look at.
How do I run opencv alone? I'm only using within eclipse.
Got it working.
ReplyDeleteThe problem was in Step 4: I did have the paths entered correctly in my Environment Variables. But I didn't have the opencv folder in the root of C:\.
Moved the folder to C:\, then updated the paths, and everything started working!
Thanks,
Wouldn't have been possible without this site!
Glad it helped!
Deletesorry for the same error, but none of the given approach worked for me
ReplyDeleteI have core i7 processor, I installed opencv 2.4.0 (which is having both 32 and 64 version all together)
used javacv 0.2 as mentioned
I have eclipse Hellios 32 bit version
so I have given the path of 32 bit opencv at system variable
But nit working.....

ReplyDeletesorry for my bad english
Hello,
ReplyDeleteIs it possible detect the face in a video file using opencv in java,if so please guide me i need it urgently....
Sorry for late reply. You can certainly do that. Look at my post on FaceDetection using Haar Classifier http://opencvlover.blogspot.in/2012/11/face-detection-in-javacv-using-haar.html
DeleteOnly thing you have to do is pass video frame instead of IplImage to the function 'cvHaarDetectObjects'.
In opencv 2.4.3 the does not appear to be a common folder so the paths listed in step 4 are correction and result in the "cant find dependent libraries" error many had above. I files are located in the gpu folder and the corrected paths are
ReplyDeleteFor 32 bit:
C:\opencv\build\x86\vc10\bin;C:\opencv\build\gpu\x86\vc10\
For 64 bit:
C:\opencv\build\x64\vc10\bin;C:\opencv\build\gpu\x64\vc10\

This issue you are facing issue mostly arises due to following reasons.
Delete1. javacv and opencv version are not compatible. i.e. you should use opencv 2.4.0 for javacv 0.2

2. One should link 32 bit opencv libs with 32 bit javacv and 64 bit opencv libs with 64 bit javacv. You should have 64 bit process in order to use 64 bit libs.

If you still have this error then try to check if opencv is installed properly on your system.

I don't know how to find the bit and version that i am using. So plz give me a solution how to find opencv and javacv bit pattern and version that i am using.
ReplyDeleteGive me the link to download the opencv and javacv both of same version and bit pattern (for both 32 and 64).
I am using win7 64 bit, jdk 32 bit whether these should be also of same bit or some thing else.
