Simoneopencv_core249d没有被指定在windows上运行,或者它包含错误
的有关信息介绍如下：
整个项目的结构图：
编写***.java,代码如下：

3.编写测试类：
[java]view
plaincopyprint?
packagecom.njupt.zhb.test;
publicclassTestMain{
publicstaticvoidmain(String[]args){
System.out.println("Hello,OpenCV");
//Loadthenativelibrary.
System.loadLibrary("opencv_java246");
newDetectFaceDemo().run();
}
}
//运行结果:
//Hello,OpenCV
//
//RunningDetectFaceDemo
///E:/eclipse_Jee/workspace/JavaOpenCV246/bin/com/njupt/zhb/test/lbpcascade_frontalface.xml
//Detected8faces
//WritingfaceDetection.png
packagecom.njupt.zhb.test;
publicclassTestMain{
publicstaticvoidmain(String[]args){
System.out.println("Hello,OpenCV");
//Loadthenativelibrary.
System.loadLibrary("opencv_java246");
newDetectFaceDemo().run();
}
}
//运行结果:
//Hello,OpenCV
//
//RunningDetectFaceDemo
///E:/eclipse_Jee/workspace/JavaOpenCV246/bin/com/njupt/zhb/test/lbpcascade_frontalface.xml
//Detected8faces
