Hello all,

I'm trying to build Native C++ Android app but i am having difficulties to load, for example, lbpcascade_frontalface.xml file from cpp file.

I have examined the samples but what i want to do is, simply something like this;


CascadeClassifier face_cascade;
while (1)
    std::vector<Rect> faces;
    face_cascade.detectMultiScale( image, faces, 1.1f, 4, CASCADE_FIND_BIGGEST_OBJECT,  Size(40, 40) );


The problem here is the path of the XML File, what should it be? The XML file can be on Assets folder or anything else in the project.

Thanks in advance.

if you bundle the cascade xml with your app, it will be zipped inside your apk. the CascadeClassifier can't read from that, so you have to copy it to e.g. sdcard temporary to use it. look at the facedetection sample how to do that
