Keine jniopencv_highgui in java.library.path

Question

Ich bin mit opencv 3.1 und nach dem gesamten Konfiguration für javacv Einstellung erhalte ich folgende Fehler

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniopencv_highgui in java.library.path

... 4 more 

Ich denke, die wegen javacv Version. Ich benutze 0.7 Version. Ich weiß nicht, welche Version mit opencv 3.1.0 tatsächlich verwendet wird und wo sie gefunden wird.

import static com.googlecode.javacv.cpp.opencv_core.*; 
import static com.googlecode.javacv.cpp.opencv_highgui.*; 
import com.googlecode.javacv.CanvasFrame; 
public class demo { 
    public static void main(String[] args) { 
    //Load image img1 as IplImage 
    final IplImage image = cvLoadImage("img1.png"); 
    //create canvas frame named 'Demo' 
    final CanvasFrame canvas = new CanvasFrame("Demo"); 
    //Show image in canvas frame 
    canvas.showImage(image); 
    //This will close canvas frame on exit 
    canvas.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE); 
    } 
}

Obiges Beispiel für mich gearbeitet 0.9 mit javacv

Hier ist der kleine modifizierte Code:

import java.awt.image.BufferedImage; 
import java.io.File; 
import java.io.IOException; 
import javax.imageio.ImageIO; 
import org.bytedeco.javacpp.opencv_core.IplImage; 
import org.bytedeco.javacv.CanvasFrame; 

public class Demo { 
public static void main(String[] args) throws IOException {   
//Load image img1 as IplImage 
    BufferedImage img = ImageIO.read(new File("C:\\Users\\Public\\Pictures\\Sample Pictures\\beach.jpg")); 
    final IplImage image = IplImage.createFrom(img); 

    //create canvas frame named 'Demo' 
    final CanvasFrame canvas = new CanvasFrame("Demo"); 

    //Show image in canvas frame 
    canvas.showImage(image); 

    //This will close canvas frame on exit 
    canvas.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);   
}  
}
