open-source NEON optimizations

Hello !

I saw in the ICVS materials that there would be an open-source code for the NEON optimizations for the OpenCV library (maybe in the 3.0 release), but at the moment it's uncertain.

I want to know more about that because I'd like to present what effect does the optimization level (prefetching, vectorizations, etc.) have on the runtime performance of computer vision algorithms on embedded platforms, and if the optimized versions are not available I'll have to write them myself (but that would contain only a few operations so that a working demo could be done and the statistics be gathered).

I'd like to mention that I'll be using an dev board with an ARM Cortex A8 core (with Mali400 GPU but I'm not aiming for using GPU).

Thanks a lot!
