Installation of javaCV

Question

I am trying to follow the instructions for installing javaCV from here: https://code.google.com/p/javacv/. I ve already built opencv. Actually I locate the java folder with .jar file and .dll in opencv folder and I add them in the path of my project. When I am trying to run the SimpleSample.java I am receiving Error: Could not find or load main class FaceRecognition. Is there something else I ve got to follow in order to install javaCV? My simple Code

 package simplesample;

 /**
 *
 * @author snake
 */

 import static com.googlecode.javacv.cpp.opencv_core.*;
 import static com.googlecode.javacv.cpp.opencv_imgproc.*;
 import static com.googlecode.javacv.cpp.opencv_highgui.*;

 public class SimpleSample{

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    // TODO code application logic here

   }
}

EDIT2: I add some jar files (javacv-windows-x86.jar, javacpp.jar, javacv.jar) and I finally got it running. But when I am trying to read a simple jpg image:

 public static void main(String[] args) {
    // TODO code application logic here
    System.out.println("soul makosa");

    IplImage image = cvLoadImage("ef.jpg");
    if (image != null) {
        cvSmooth(image, image, CV_GAUSSIAN, 3);
        cvSaveImage("ef1.jpg", image);
        cvReleaseImage(image);
    }

}

I am reveiving the following errors:

... 4 more
   Java Result: 1

I also add .dll file in properties->run->VM optimize as instructed here giving 'java.library.path' in netbeans for .dll/.so files. However I am still receiving the above message.

Solution 1

SOLVED:Ok my problems was due to the fact that I had to install specific version of javaCV. So for openCV version 2.4.6.1 I ve installed 0.6 java_CV and now works like a charm.

Solution 2

You need to add native class library path while adding opencv jar file into the project

Goto the buildpath>>libraries>>opencv >> click on expand and edit " native library location" to

C:/opencv/build/java/x86

for face FaceRecognition you need to add all jar files from that site

javacv-0.7-bin.zip javacv-0.7-cppjars.zip ffmg, etc....

it will work .... Its working for me
