In this paper, we present a novel visual speed limit signs detection and recognition system. In detection stage, for the purpose of reducing the computational load and further decreasing the error detection rate of speed limit sign, a novel de-noising method based on HOG is presented and apply it to Fast Radial Symmetry Transform approach for circle signs… CONTINUE READING
