테스트 프로젝트 생성 및 소스 코드 추가

Now you have created and configured a new Java project it is time to test it. Create a new java file. Here is a starter code for your convenience:

import org.opencv.core.Core;
import org.opencv.core.CvType;
import org.opencv.core.Mat;

public class Hello
{
  public static void main( String[] args )
  {
     System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
     Mat mat = Mat.eye( 3, 3, CvType.CV_8UC1 );
     System.out.println( "mat = " + mat.dump() );
  }
}

When you run the code you should see 3x3 identity matrix as output.
