Real-Time Speed Sign Detection Using the Radial Symmetry Detector

Barnes, Nick; Zelinsky, Alex; Fletcher, Luke


Algorithms for classifying road signs have a high computational cost per pixel processed. A detection stage that has a lower computational cost can facilitate real-time processing. Various authors have used shape and color-based detectors. Shape-based detectors have an advantage under variable lighting conditions and sign deterioration that, although the apparent color may change, the shape is preserved. In this paper, we present the radial symmetry detector for detecting speed signs. We...[Show more]
