Hi mphong,
The opencv4tegra provided by NVIDIA was containing optimizations for NVIDIA’s Tegra CPUs (ARM NEON SIMD optimizations, multi-core CPU optimizations and some GLSL GPU optimizations).
The others are public source.
But as your description, you want to use some new functions in opencv 3.0, then you should continue use opencv 3.0 on both client TX1 device and host PC.
Thanks
