2012-12-04 10:00:04 -0600	answered a question	what is the best matching method for freak? It is slow because SSSE3 is not enabled in OpenCV. I believe this is an issue. See my question. I'd be interested to know if you've found how to work it out since the time you posted here.
2012-12-04 09:57:18 -0600	answered a question	How to use SSSE3? I've been able to use SSSE3 but i had to dig into core OpenCV code. I used the author's code. I don't have any better approach as yet. In fact i also have a question on the subject here.
2012-12-04 09:52:17 -0600	asked a question	How can i use a custom norm with BruteForceMatcher ? I was trying to use FREAKS (https://github.com/kikohs/freak) & BRISK (http://www.asl.ethz.ch/people/lestefan/personal/BRISK) author's code. They both define custom Hamming norms to use SSSE3 instructions. Only there's a major difference between 2.3.x and 2.4.x in BruteForceMatcher. Since commit 957e80ab, BruteForceMatcher takes an (int normType) instead of a Distance. Thus their code using custom norms is now broken, and I don't quite see how to use a custom distance without modifying library code. The only solution i have seen up to now is add a <custom_norm_type> to the enum list in core.hpp (l.124) add calls to the custom norm function in similar ways than where NORM_HAMMING is used, i.e. lots of changes in core/src/stat.cpp Now i have to recompile OpenCV & use a custom version. This is annoying. If you check the links above, you'll see how much more practical it was before. So what do you recommend now?
