Dependent Libraries opencv_legacy #304

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Try to use Loader.load(opencv_legacy.class);
or use one of it's functions (cvCalcEigenObjects in this case)

What is the expected output? What do you see instead?
I'm getting
java.lang.UnsatisfiedLinkError: 
C:\Users\Admin\AppData\Local\Temp\javacpp311197809812598\jniopencv_nonfree.dll: 
Can't find dependent libraries

What version of the product are you using? On what operating system?
JavaCV 0.5 on Windows 8 x64

Please provide any additional information below.
I'm using the precompiled CPPJars, all jar files included in my project:

Also tried adding the DLL files to classpath and even putting them manually in 
the tmp folder (As I thought it might be a naming mismatch somewhere in the 
Java code)

And my last attempt before giving up was to use the official OpenCV DLL files, 
which also failed

Thanks for reporting this issue! I think I fixed the cause in this commit:
http://code.google.com/p/javacv/source/detail?r=42b41d0a1b208ab9a8cf71b1830cad1f

You can get an updated javacv.jar by calling, for example:
    > mvn package -Pffmpeg,videoinput -Djavacpp.skip=true
Does that fix the problem?

Seems to be fixed. Thanks!

I am also getting similar error
C:\Users\AppData\Local\Temp\javacpp286444757914917\jniopencv_nonfree.dll: Can't 
find dependent libraries
when using CvSURFParams params = cvSURFParams(500,1);
How can I obtain the updated javacv.jar file for a non-mavenized project?
Thanks!

@all.shyam
My project isn't 'mavenized' either, I cloned JavaCV and built it from source 
using the maven command samuel posted.

However, I do understand using Maven is a hassle so here you go

@giedoterol , Hi could you please upload the javacv.jar again ? :)

Guess more people don't like Maven...

This is the last time I'll be posting a link though, it's not much of an effort 
to enter the command Samuel posted

I made one myself but it's introducing another error even before reaching the 
line of the last error:
OpenCV Error: Bad argument (Different sizes of objects) in cvCalcEigenObjects, 
file ..\..\..\src\opencv\modules\legacy\src\eigenobjects.cpp, line 1363
Exception in thread "main" java.lang.RuntimeException: 
..\..\..\src\opencv\modules\legacy\src\eigenobjects.cpp:1363: error: (-5) 
Different sizes of objects in function cvCalcEigenObjects
any ideas ?
yours is no different either unfortunately :(

I've had a lot of problems while doing my project using JavaCV
One of the problems was that the images used for training needed to be the 
exact same size.
I think that was the same error you're getting right now. Are you using images 
of different dimensions?

They have different sizes yes, but it was ok before I resized them, they were 
too big and made a 2.6 GB xml so I tried to make them smaller and this happened 
!
P.S. Removing some of the images did the trick. Thanks !

@giedoterol You seem to have a pretty good grip on javaCV's problems do you 
know why the xml files created using cvWrite are so large ? (around 2 GB)

I've changed a lot of things w.r.t to dependency management in JavaCPP 0.6 and 
JavaCV 0.6. It should all work better now, but please let me know if any new 
problem pops up, thanks!

I am now getting this error.

I am trying to do feature detection, and during my search I found examples

"ObjectDetection.java"

I cannot find the class for some reason, but it's one of the examples from 
JavaCV.

OpenCV Error: The function/feature is not implemented (OpenCV was built without 
SURF support) in cvExtractSURF, file 
..\..\..\..\opencv\modules\legacy\src\features2d.cpp, line 77
Exception in thread "main" java.lang.RuntimeException: 
..\..\..\..\opencv\modules\legacy\src\features2d.cpp:77: error: (-213) OpenCV 
was built without SURF support in function cvExtractSURF

    at com.googlecode.javacv.cpp.opencv_legacy.cvExtractSURF(Native Method)
    at imagerecognition.FeatureDetection.setSettings(FeatureDetection.java:145)
    at imagerecognition.FeatureDetection.<init>(FeatureDetection.java:54)
    at imagerecognition.FeatureDetection.main(FeatureDetection.java:373)
Java Result: 1

Then after the weird error, I found another example using SURF, which was 
extremely basic.

    static public void detect() {
        final IplImage image = cvLoadImage("image");
        final KeyPoint keyPoints = new KeyPoint();
        final SURF surf = new SURF(2500, 4, 2, true, false);
        // JVM crashes when JavaCV native binaries and OpenCV binaries are build with different versions of VisualStudio
        // For instance, JavaCV is build with VC10 and OpenCV with VC11.
        surf.detect(image, null, keyPoints);

    }

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniopencv_nonfree 
in java.library.path
    at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1857)
Java Result: 1

So I'm assuming they both have to do with this?

I'm using the newest JavaCV, I believe 0.7, downloaded January 7th of this 
year(a day after the new update).

I would try the fixes above, but I'm not sure if that's 0.6 javacv jar or not, 
so I'll wait and see

Thanks

@ExoticDriedMeats The changes in this revision should fix that:
