Hi,

I saw changelogs of OpenCV 3:

About 40 commonly used image processing functions have been optimized using vector NEON instructions, so OpenCV 3.0 beta should run noticeably faster on modern ARM chips. Big thanks to Ilya Lavrenov for the amazing job!

Could anyone tell me that how to make sure I'm running the code with NEON support? Should I build OpenCVForAndroid from trunk by myself? Or taking the library from the link is enough? http://sourceforge.net/projects/openc...

Thanks

it should be used automatically, afaik, there's nothing required to do on your side.

I found the instruction of buildingOpenCV4Android mentions Android hardware targets. I will follow it and check the difference.

How to do that ? do you have compile with NEON OPTIMIZATIONS ? Because i meet a lot of errors when i want to compile any version of opencv with NEON support.
