Optimization of OpenCV on android (neon-instruction, GLSL on tegra 3 )

Question

I am now using some OpenCV functions in my Android application development. Since the frame rate is quite critical for the program, I am wondering how could I enable the optimization of OpenCV on android, since I have read about the newest version (2.4) of OpenCV use neon-instruction and GLSL for acceleration, is it automatically enabled? Or anything I need to put in the Android.mk file for compiling? (P.S. the Opencv Manager on android automatically download the "OCV 2.4 pack NVIDIA Tegra 3" alr)

Answer 1

The "OCV 2.4 pack NVIDIA Tegra 3" package contains NEON and GLSL optimizations of OpenCV.

If you use OpenCV Manager API for OpenCV initialization it uses the optimized libs automatically.
