Android : rescaling of image before detection

[Ashok Bugude]

I have tested a set of sample images for face detection using

1. Python - face_detector.py
2. C++ - face_detector_ex.cpp
3. Android Face Detection

I have found that small faces are getting detected in

1. Python - face_detector.py
2. C++ - face_detector_cpp.cpp

But not detected in Android Face Detection.

I have found that image is rescaled to bigger size using the following methods so that small faces are detected

1. Python - face_detector.py [ detector(img,1)]
2. C++ - face_detector_cpp.cpp [ pyramid_up(img) ]

Can I please know if the image is also rescaled in android (in jniDetect) function.
If so , can I please know the location of the code
If not, can I please know which location do I need to scale the image
