how about amd-x64 platform in windows?

Closed this issue 9 years ago · 26 comments

Is there an existed version for amd-64 dll with maven install.
like:

org.javaopencvbook
opencvjar-runtime
3.0.0
natives-windows-x64

or
i could run x32 in x64 platform?

but i get an error :
Can't load IA 32-bit .dll on a AMD 64-bit platform.

Sure, use

org.javaopencvbook
opencvjar-runtime
3.0.0
natives-windows-x86_64

In your pom.xml
Please, notice the x86_64.
It should work.
I believe that if you have 32bit JRE, it should work with the x32 version.

Hi, have some code issues in Computervision with Java . Background project in chap.6, App.java. Netbeans generates errors. 1. Error : incompatible types, MixtureOfGaussianBackground cannot be converted to VideoProcessorBackground (videoProcessor = new MixtureOfGaussianBackground();)
2. Error: cannot find symbol method process(Mat) (foregroundImage = videoProcessor.process(currentImage);) can you please help me? All other code works fine.

Answer 6 · 2016-05-24T03:50:03.000Z

Hi. Would you mind opening another thread for this issue? It might happen that people get updated about the other topic.

Well, regarding your problem, that's weird, because class MixtureOfGaussianBackground implements the VideoProcessor interface... like this:
public class MixtureOfGaussianBackground implements VideoProcessor

It could be a typing error... you said it cannot be converted to VideoProcessorBackground.
But line 63 states:
VideoProcessor videoProcessor;
and not
VideoProcessorBackground videoProcessor;
Are you sure you got that line correct?
I believe error 2 is related to this one, so if you correct that, this one will be done.
Please, check that.
Kind regards,
Daniel

Hi, in the first picture you can see how the original source for app.java
looks. The constructor-bit for MixtureOfGaussian looks Strange and
generated error. In the second picture you can see how I altered the
source code to make it run. As I made my own import-statements to point to
my folder structure and adding the background suffix where appropriate
, the Videoprocess Class has suffix of background as its part of the the
background project. The projects now runs.

Hi.
I can't see the pictures.
Can you post them again, please?
I find it weird that it wasn't compiling.

Answer 9 · 2016-05-24T21:32:21.000Z

Answer 10 · 2016-05-24T22:14:47.000Z

Well, they still haven't come...
Either way, the code from the book goes like this:
https://github.com/JavaOpenCVBook/code/blob/master/chapter6/background/src/main/java/org/javaopencvbook/App.java

private void runMainLoop(String[] args) throws InterruptedException {
        ImageProcessor imageProcessor = new ImageProcessor();
        Image tempImage;        
        VideoProcessor videoProcessor;
        VideoCapture capture = new VideoCapture("src/main/resources/videos/tree.avi");

        if( capture.isOpened()){

            capture.read(backgroundImage);

            //videoProcessor = new AbsDifferenceBackground(backgroundImage);
            //videoProcessor = new RunningAverageBackground();
            videoProcessor = new MixtureOfGaussianBackground();

You can create a reference to the VideoProcessor interface like this:

VideoProcessor videoProcessor;

you will only instantiate the object whose class implements the VideoProcessor interface afterwards, like this:

videoProcessor = new MixtureOfGaussianBackground();

Of course, you can also write it all in a single sentence, like you said:

VideoProcesso videoProcessor = new MixtureOfGaussianBackground();

or

VideoProcessorBackground videoProcessor = new MixtureOfGaussianBackground();

Both approaches should work.

Ok, thank you so much, I appreciate the help very much.

Answer 14 · 2016-06-23T10:49:31.000Z

Am trying to run maven project with:

org.javaopencvbook
opencvjar-runtime
3.0.0
natives-windows-x86

And it says that maven dependency not found , any help ?

Answer 15 · 2016-06-23T17:42:37.000Z

I believe this is probably because you haven't added the OpenCVBook repository, like this:

<repositories>
    <repository>
        <id>javaopencvbook</id>
        <url>https://raw.github.com/JavaOpenCVBook/code/maven2/</url>
    </repository>
</repositories>

Can you send us your full pom.xml to check that?
Also, can you copy and paste the maven output?

Kind regards,
Daniel

Answer 16 · 2016-06-24T08:16:17.000Z

Problem with

org.javaopencvbook
opencvjar-runtime
2.4.7
natives-windows-x86_64

As I am trying to use it on Mac , could you help or provide any other maven dependancy I could use ?

Answer 17 · 2016-06-24T08:42:29.000Z

And one more image with mac native:
Also I tried changing to different versions

Answer 18 · 2016-06-24T08:55:36.000Z

And output from mvn

Answer 19 · 2016-06-24T12:09:25.000Z

Hi Vasilij,

actually, there aren't mac natives for 2.4.7.
You can use the 2.4.8 version:
2.4.8-natives-mac-x86_64.jar
https://github.com/JavaOpenCVBook/code/blob/maven2/org/javaopencvbook/opencvjar-runtime/2.4.8/opencvjar-runtime-2.4.8-natives-mac-x86_64.jar
I can't test right now, but changing your versions of opencvjar and
opencvjar-runtime to

2.4.8
should work.
You can browse available files here:
https://github.com/JavaOpenCVBook/code/tree/maven2/org/javaopencvbook/opencvjar-runtime

If you could provide the 3.0.0 mac runtimes I can put them on the server as
well.

Please, write back in case it works or not.

Kind regards,
Daniel

Answer 23 · 2016-06-24T13:13:06.000Z

Here you go, I think that I have additionally provide jenkins java.library.path for opencv_java248.jar ?

Answer 24 · 2016-06-24T13:24:45.000Z

I figured it out, yap all is good with maven, I had to specify where is the library jar for openCV , so basically instead of using :
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
I used:
System.load("full path to maven downloaded jar ");

And it works fine :)

Thank you all for helping me.

Sincerely

Answer 25 · 2016-06-24T15:53:22.000Z

Nice it has worked, and you've documented the solution :)

Kind regards
