java - 图像处理库

Question

我最近下载了 OpenCv 库，我正在尝试使用它的功能，但不幸的是我无法这样做。这是我编写的类

/*

 */
package Opencv;

import hypermedia.video.*;

/**

 * @author 

 */
public class LoadImage
{
    public LoadImage()
    {


        OpenCV opencv = new OpenCV( );
        opencv.loadImage( "one.png", 200, 100);
        image( opencv.image(), 0, 0 );
      //  image( opencv.loadImage("one.png.jpg"), 0, 0);


    }


    public static void main(String[] args)
    {
               LoadImage im=new LoadImage();
    }
}

我正在使用 netbeans IDE，它没有显示任何语法错误。但是在运行它之后我得到以下错误。

!!! required library not found : C:\Program Files\Java\jdk1.6.0_21\bin\OpenCV.dll: Can't find dependent libraries
Verify that the java.library.path property is correctly set and the '\path\to\OpenCV\bin' exists in your system PATH

Exception in thread "main" java.lang.UnsatisfiedLinkError: hypermedia.video.OpenCV.loadImage(Ljava/lang/String;II)V
    at hypermedia.video.OpenCV.loadImage(Native Method)
    at Opencv.LoadImage.<init>(LoadImage.java:20)
    at Opencv.LoadImage.main(LoadImage.java:30)
Java Result: 1
BUILD SUCCESSFUL (total time: 6 seconds)

但是我已经完成了导入库中的所有操作，几乎在任何地方都放置了 OpenCv.dll 文件。但我一直收到此错误。帮助

看来 java 找不到合适的 DLL - openCV 是通过 JNI 调用的。这是有用的答案: OpenCV to JNI how to make it work?
