Android face-detection sample: where's the native code?

Hi.

I have been looking at this face-detection sample, but I cannot seem do get access to the C++ native source code. I'm new to JNI, I must confess...

As far I understand, this native part of the project is only available as a shared library in libs/<arch>/libdetection_based_tracker.so

Since I want to do some changes to that code, I would need to access and change the source. Is it available somewhere? Am I missing something?

Bye and thanks, Luís

are you saying, you can#t find the source code ?

it's in OpenCV/samples/face-detection/jni/DetectionBasedTracker_jni.cpp

Hello berak.

If I understand things right, in the file you mention you cannot find the actual c++ source code, that's just the code to bridge from java to c++: it simply calls the actual c++ code and deals with exceptions and other bits and pieces.

If, eg, you look at Java_org_opencv_samples_facedetect_DetectionBasedTracker_nativeDetect, you'll see that some methods are being called, like process and getObjects. What I'm looking is for the definition of these methods.

Thanks anyway.

ah, sorry took the jni code for another haarcascade wrapper, but instead it wraps a completely different class.

the DetectionBasedTracker is in the contrib module, header , src

but to modify it, you'll probably need the opencv src code

Yeah, you're right, I just had found those files myself! There should be some link to these files in the sample, or else this problem might arise again...

Thanks, Luís
