你如何通过标签参数为（MAT）来自OpenCV的Java中facerecognizer？ [英] How do you pass the labels parameter as a (Mat) to facerecognizer from OpenCV in Java?

问题描述

所以我想实现从Android上OpenCV的API的贡献部分的脸部识别方法。 API文档可以在这里找到： http://docs.opencv.org /modules/contrib/doc/facerec/facerec_api.html

So I'm trying to implement the Face Recognizer methods from the contributed section of the OpenCV API on Android. The API documentation can be found here: http://docs.opencv.org/modules/contrib/doc/facerec/facerec_api.html

我遇到的问题是，Java API中，火车的方法是：

The problem I'm having is that in the Java API, the train method is:

public  void train(List<Mat> src, Mat labels){
    Mat src_mat = Converters.vector_Mat_to_Mat(src);
    train_0(nativeObj, src_mat.nativeObj, labels.nativeObj);

    return;
}

我不能为我的生命，让调用，因为（MAT）的工作标签输入。在C ++文档，它要求一个整数向量，所以我想通过一维垫，但没有运气。任何人有这个问题或对如何解决这个一些见解？

I cannot for the life of me, get the call to work because of the (Mat) labels input. In the c++ documentation it calls for a vector of integers, so I tried passing a 1D Mat, but no luck. Anyone had this problem or have some insight on how to tackle this?

推荐答案

哦，亲爱的，貌似你有没有发现，你不能的创建的一个FaceRecognizer在OpenCV中的Java API截至目前？

oh dear, looks like you haven't found out, that you cannot create a FaceRecognizer in the opencv java api as of now ?

这是一个已知的错误，你就需要一些技巧JNI建工厂缺少的功能。

it's a known bug, you would need some jni skills to build the missing factory functionality.

除非你解决这个问题，不用担心标签...

unless you solve that, don't worry about the labels ...
