- W2273527720 abstract "We present an original approach regarding the robust automatic detection of vertical danger road signs under natural light. The detector is based on the combination of template shapes and an optimization algorithm called evolution strategy hybridized with a local search method of the conjugate gradient kind. The pre-detection step uses a computation of chromatic dominance robust to uncontrolled illumination conditions. Using a template shape helps reducing the sensitivity to noise. The cost function is the sum of a priori terms and of two likelihood terms. The adjustment of the detection threshold and the global performance evaluation of the detector are founded on ROC curves." @default.
