使用javacv进行人脸识别是行不通的

我正在java上做一个关于人脸识别的项目。为此，我使用opencv库。但我不知道如何在没有任何其他库的情况下直接从opencv调用人脸识别方法。因此，现在我正在使用javacv。但当我尝试代码时，这两行显示红线。 FaceRecognizer FaceRecognizer=createEigenFaceRecognizer。 MatVector images=新MatVectorimageFiles.length

我试图导入相应的软件包，但无法正常工作。有人能帮我吗？如果有人知道如何仅使用opencv库实现人脸识别，那么请plzz帮助我。提前感谢

您实际遇到的编译器错误是什么？错误是在OpenCVFaceRecognitizer类中找不到symbol CreateGeneFaceRecognitizer。您是否确保在类路径中包含JavaCV引用的必要JAR？另请参阅其中涉及的代码示例完全相同我已将JavaCV和opencv JAR导入程序。
