Abstract

Abstract — Traffic sign recognition has been a recurring appli-cation domain for visual objects detection. The public datasets have only recently reached large enough size and variety to enable proper empirical studies. We revisit the topic by showing how modern methods perform on two large detection and classification datasets (thousand of images, tens of categories) captured in Belgium and Germany. We show that, without any application specific modification, existing methods for pedestrian detection, and for digit and face classification; can reach performances in the range of 95 % ∼ 99 % of the perfect solution. We show detailed experiments and discuss the trade-off of different options. Our top performing methods use modern vari-ants of HOG features for detection, and sparse representations for classification. I.
