Hi everyone,

I'm trying to get the OpenCV library up and going with Eclipse - I got it running with the included Java examples, but get stuck when trying to use the Processing + OpenCv example- here's the code and the error. Any info would be great-

Thanks
Jon



import processing.core.*;
import hypermedia.video.OpenCV;



public class OpenCV_PApplet extends PApplet {



OpenCV cv = null;
// OpenCV object



/**

* Initialise Objects.

*/

public void setup() {



// PApplet setup


size( 640, 480 );


background(0);




// OpenCV setup


cv = new OpenCV( this );


cv.capture( width, height );

}



/**

* Display the input video stream in invert mode.

*/

public void draw() {


cv.read();


cv.invert();


image( cv.image(), 0, 0 );

}



/**

* Call the PApplet main method.

*/

public static void main( String[] args ) {


System.out.println( "\nOpenCV meet Processing PApplet\n" );


PApplet.main( new String[]{"OpenCV_PApplet"} );

}

}
 


Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: processing/core/PImage

okay, I'm trying to troubleshoot all this, here's what i've tried.

-displayed a PImage directly from a jpg- no issues. Still crashes when trying to display at

image( cv.image(), 0, 0 );

-I've also tried different core.jar files from different processing version, ya know some funky interconnection problem? 0135, 1.0.1, 1.0.3 - no luck.

unfortunately for me this project is really stuck if i don't get opencv going. -is there another library that will give me the center x,y of a tracked blob?


thanks
