Hi!

I'm a newbie here, so be gentle, please ^^U

I'm trying to make a traffic signs recognition with Java for my Final Work on university; and I'm full of questions. To achieve this, I was basing my work on FLANN Based.

Because after some research I think FLANN algorithm might be my best choice (Correct me if wrong).

However, when I try to compile the project I get "OpenCV Error: Bad argument (Specified descriptor extractor type is not supported.) "

I'm using:
FeatureDetector: FAST
DescriptorExtractor: SURF
DescriptionMatcher: FLANNBASED

"I'm trying to make a traffic signs recognition " -- what does that mean, exactly ?

(if you try to detect & classify different signs, this is the wrong algorithm for it)

"Specified descriptor extractor type is not supported." - you cannot use SIFT or SURF from java.

The idea is a camera in an Android Auto ti be recording and checking every second (for example) the snapshot and check if there is any known signal there. (Actually only the speed limit)

If I can't use SIFT or SURF what would be my best choice? PD: I've read about this ASIFT algorithm that looks pretty cool. Can I use it from OpenCv3?
