An embedded system for real-time traffic sign recognizing

Automated recognition of traffic signs is an important issue for driver assistance and autonomous navigation systems. Those systems have to be fast and robust to detect signs in real-time and recognize them precisely. In this paper, we present a HW/SW system for detection and recognition of circular traffic signs mainly based on color and shape properties. The designed system has been implemented in a CYCLONE II DE2 Board using the Nios II softcore processor which is characterized by its flexibility and programmability.
