Installation of javaCV
提问by snake plissken
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
我正在尝试按照以下说明安装 javaCV：https: //code.google.com/p/javacv/。我已经构建了 opencv。实际上，我在 opencv 文件夹中找到了带有 .jar 文件和 .dll 的 java 文件夹，并将它们添加到我的项目路径中。当我尝试运行 SimpleSample.java 时，我收到错误：无法找到或加载主类 FaceRecognition。为了安装javaCV，我还需要遵循什么吗？我的简单代码
package simplesample;
/**

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:
EDIT2：我添加了一些 jar 文件（javacv-windows-x86.jar、javacpp.jar、javacv.jar），我终于让它运行了。但是当我试图读取一个简单的 jpg 图像时：
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:

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.
我还在属性-> 运行-> VM 优化中添加 .dll 文件，按照此处的说明在 netbeans 中为 .dll/.so 文件提供“java.library.path”。但是我仍然收到上述消息。

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.
已解决：好的，我的问题是由于我必须安装特定版本的 javaCV。所以对于 openCV 版本 2.4.6.1 我已经安装了 0.6 java_CV 并且现在就像一个魅力。

You need to add native class library path while adding opencv jar file into the project
项目中添加opencv jar文件时需要添加原生类库路径
Goto the buildpath>>libraries>>opencv >>click on expand and edit " native library location" to
转到构建路径>>库>>opencv >>单击展开并编辑“本机库位置”以
C:/opencv/build/java/x86
C:/opencv/build/java/x86
for face FaceRecognition you need to add all jar files from that site
对于 face FaceRecognition，您需要从该站点添加所有 jar 文件
javacv-0.7-bin.zip javacv-0.7-cppjars.zip ffmg, etc....
javacv-0.7-bin.zip javacv-0.7-cppjars.zip ffmg 等...
it will work .... Its working for me
它会工作......它对我有用
