Hi! I am trying to recognize traffic signs, I already detect them, but now I have to do something to know which one is each of them, I have been reading about the cascade classifier but i would need 1 for each sign right? Furthermore i am having some issues with the merging of vec files. What do you recommend me to use for this object recognition? i am not sure if the cascade classifer is the best method.....

Thanks a lot fot your help!!

If you have already located them, then using a cascade classifier, which is a detector/locator will not help you there. The following step you should do is a feature detector and matcher against a known class. This will work much better.

You should start reading on the features2D module, right here!

in thar module it uses surf detector, i tried that but i havent got good results, i have to calculate descripitors of all traafic roads and compare them my imae detected and the smalles distance is the best result? because I tried that once and it did work quite well
