I noticed in later OpenCV 3.2 changelog that "NVidia corporation has donated ARM optimizations for OpenCV, the Carotene library (https://github.com/opencv/opencv/tree/master/3rdparty/carotene)."
Is it currently integrated with OpenCV 3.2 binaries for iOS or is it in the form of OpenVX library and OpenCV framework for iOS have to be recompiled? Are there any instructions how to enable Carotene Acceleration in OpenCV 3.2 for iOS?
