摘要
Abstract
A traffic sign detection algorithm based on the regions of interest and Histogram of Oriented Gradient and Census Transform Histogram is proposed. Firstly,the color threshold segmentation is performed in the HSV color space,then a series of morphological processing is performed on the segmented binary image to obtain the regions of interest,finally,the HOG-CTH fea?tures of the regions of interest are extracted,and the support vector machine(SVM)classifier is used to carry out traffic sign train?ing and detection.Firstly,the features of the Histogram of Oriented Gradient(HOG)and the Census Transform Histogram(CEN?TRIST/CTH)are extracted respectively in the stage of feature extraction. Then the CTH feature vector is refined.Finally,HOG and sparsed CTHfeatures are combined. The experimental results show that the method has good robustness and can detect the traffic signs quickly and accurately.关键词
