Java OpenCV Android完全使用c++；

我注意到github中的大多数Android示例都使用java中的opencv。我现在在iOS中有一个可用的应用程序，我尽力将opencv调用与桥接头分开

在安卓系统中也可以这样做吗？我注意到OpenCV检测器像CasCADECLSILIVER都是java，C++中没有。

在Android中，我能实现与iOS一样的事情吗？

< P> < St>你可以完全使用C++，并且必须使用JNI让java代码调用本地代码。< /强> < /P> 下载Opencv android sdk后，您只能导入所需的头文件和“.a”文件。java文件是为那些不知道C++的人提供的。 例如，java类CascadeClassifier，最后称为本机函数，您也可以这样做，实际上，它是JNI：

 // C++:   CascadeClassifier::CascadeClassifier()
private static native long CascadeClassifier_0();

// C++:   CascadeClassifier::CascadeClassifier(string filename)
private static native long CascadeClassifier_1(String filename);

// C++:  void CascadeClassifier::detectMultiScale(Mat image, vector_Rect& objects, double scaleFactor = 1.1, int minNeighbors = 3, int flags = 0, Size minSize = Size(), Size maxSize = Size())
private static native void detectMultiScale_0(long nativeObj, long image_nativeObj, long objects_mat_nativeObj, double scaleFactor, int minNeighbors, int flags, double minSize_width, double minSize_height, double maxSize_width, double maxSize_height);
private static native void detectMultiScale_1(long nativeObj, long image_nativeObj, long objects_mat_nativeObj);

// C++:  void CascadeClassifier::detectMultiScale(Mat image, vector_Rect& objects, vector_int rejectLevels, vector_double levelWeights, double scaleFactor = 1.1, int minNeighbors = 3, int flags = 0, Size minSize = Size(), Size maxSize = Size(), bool outputRejectLevels = false)
private static native void detectMultiScale_2(long nativeObj, long image_nativeObj, long objects_mat_nativeObj, long rejectLevels_mat_nativeObj, long levelWeights_mat_nativeObj, double scaleFactor, int minNeighbors, int flags, double minSize_width, double minSize_height, double maxSize_width, double maxSize_height, boolean outputRejectLevels);
private static native void detectMultiScale_3(long nativeObj, long image_nativeObj, long objects_mat_nativeObj, long rejectLevels_mat_nativeObj, long levelWeights_mat_nativeObj);

// C++:  bool CascadeClassifier::empty()
private static native boolean empty_0(long nativeObj);

// C++:  bool CascadeClassifier::load(string filename)
private static native boolean load_0(long nativeObj, String filename);

// native support for java finalize()
private static native void delete(long nativeObj);
