OpenCV 2.4.13.4 dll链接错误

Question

我正在为OpenCV运行以下代码段：

public static void main(String[] args){

System.out.println("Welcome to OpenCV " + Core.VERSION);
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
Mat m  = Mat.eye(3, 3, CvType.CV_8UC1);
System.out.println("m = " + m.dump());
}

我收到此错误：

Welcome to OpenCV 2.4.13.4
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_eye(III)J
    at org.opencv.core.Mat.n_eye(Native Method)
    at org.opencv.core.Mat.eye(Mat.java:1468)
    at HelloCV.main(HelloCV.java:29)

我尝试了以下内容：

1. 将dll完整路径名放在System.loadLibrary
上
2. 将dll路径传递给JVM
3. 将dll文件放入windows system32文件夹
4. 将dll路径名放入eclipse opencv.jar config
