Abstract
Embodiments provide a method for recognizing a traffic sign from an input image. The method may include extracting image features from the input image; modifying the image features based on a predetermined image saliency map to determine modified image features; determining a plurality of traffic sign candidates by applying an adaptive boosting algorithm on the modified image features; determining a confidence score for each traffic sign candidate by applying a support vector regression algorithm; and recognizing a traffic sign based on the confidence score for each traffic sign candidate.
