OpenCV speed traffic sign detection

Question

I have a problem detecting speed traffic signs with opencv 2.4 for Android. I do the following:

\"capture frame -> convert it to HSV -> extract red areas -> detect

Answer 1

have you tried using opencv ORB? it works really well. I created a haar cascade for a traffic sign (roundabout in my case) and used opencv ORB to match features and remove any false positives. For image recognition used Google's tensorflow and results were spectacular.
