“ : : :The detection and classification methods are as shown in Fig. 2 are (1) Haar-like features with Adaboost classifiers, (2) histogram of oriented gradients with support vector machine classifiers, and (3) a new variant of HOG features where histogram of local color distributions are formed and concatenated with the HOG descriptors (Memarzadeh et al. 2013) to leverage both shape and color information for multiple traffic sign category with one-versus-all SVM classifiers.”
