Other programs on javac showImage.java and motion detection works fine .

And which version of OpenCV?

Original comment by samuel.a...@gmail.com on 7 Feb 2012 at 4:01

I got the same error;
javacv-bin-20120108 version and openCV2.3.1

I reference to the sample:
http://www.cnblogs.com/ljsspace/archive/2011/08/05/2128948.html

except different versions.

when I changed openCV version to 2.3, got other error:

OpenCV Error: Null pointer (Invalid classifier cascade) in unknown function, 
file C:\slave\WinInstallerMegaPack\src\opencv\modules\objdetect\src\haar.cpp, 
line 1041

Could you let me know the content of your system PATH? thanks

[GoogleCodeExporter]

I put all files in OpenCV2.3.1\build\x86\vc10\bin into C:\Windows\System32 
folder.

Please try to remove the files from there, and follow the instructions on this 
page: 
http://code.google.com/p/javacv/wiki/Windows7AndOpenCV
And let me know if this fixes the problem, thank you

I follow the instructions
http://code.google.com/p/javacv/wiki/Windows7AndOpenCV

and tried both but still not work:

here is my FaceDetection file.

I add OpenCV DLLs and tdd.dll to system PATH C:\Windows\System32

Can you try to run the Demo class in the README.txt instead? Thank you

Original comment by samuel.a...@gmail.com on 14 Feb 2012 at 1:16

[GoogleCodeExporter]

Demo class in README.txt ran well. thx.

but why the FaceDetection cannot work?

Original comment by xuzhike1...@gmail.com on 15 Feb 2012 at 12:24

[GoogleCodeExporter]

Probably because of this missing line:
        // Preload the opencv_objdetect module to work around a known bug.
        Loader.load(opencv_objdetect.class);

Judging by the lack of feedback, I assume the issue has been resolved. Please 
let me know if this is not the case.

Thank u very much , the issue was with the JavaCV version 

Original comment by free4st...@gmail.com on 11 May 2012 at 11:05

[GoogleCodeExporter]

I get the same errors, could you please share which JavaCV version is needed to 
make the FaceDetection work?
Thank you

I got "Invalid classifier cascade" error when the CASCADE_FILE was not put in 
the location my code is looking for. The error is gone once I fixed the 
location. It also looks like the DLLs are loaded based on the exact name match, 
so the currnt 0.1 version only works with OpenCV 2.4.0.

I tried OpenCV 2.4.1 and was able to overcome the first "Can't find dependent 
libraries" error by renaming opencv_core241.dll and opencv_core241d.dll to 
opencv_core240.dll and opencv_core240d.dll. It then complained the same error 
with a different jniopencv_xxx.
