| 摘 要： | 为满足汽车安全性的要求,基于图像的梯度方向直方图特征,利用支持向量机的方法,实现了行人检测。该方法提取正负样本图像的局域梯度直方图特征,利用支持向量机进行样本训练,得到行人分类器。利用训练好的分类器进行检测,实验结果表明,该方法可以有效检测出前方出现的行人,并达到了较好的检测效果。

| Abstract: | To meet the requirement of vehicle safety,a method based on Histograms of Oriented Gradients(HOG) and Support Vector Machine(SVM) which can be used to detect the preceding human is presented.Calculation is done to get some part of HOG feature in some positive and negative training examples.Then the algorithm of SVM is used to do the training to get a human classifier.Then,the classifier is used to make human detection.Experiment results are performed practically and show that the proposed method can detect ... |
