ABSTRACT:
A method recognizes a set of traffic signs in a sequence of images acquired of a vehicle environment by a camera mounted in a moving vehicle by detecting in each image, a region of interest (ROI) using a parameter space transform. The ROI is tracked and classified as a particular one of the signs. The classifier only uses a same class and a different class, and a regression function to update the classifier.
