HOG+SVM 应用OPENCV来检测人体图像中是否有人-HOG+SVM application the OPENCV to detect whether someone in the human body image

基于hog特征与支持向量机的方式，使用opencv自带的haar特征分类器，检测人脸-Adapt to hog feature and support vector machine (SVM) method, based on positive and negative samples opencv training face,

将样本分类为正样本，负样本，难以辨别样本，依次标记为1，-1，-1，通过hog计算各类样本特征，以xml形式写入vsm模型。测试样本时，只需要加载xml文件，计算出测试样本的hog特征，通过预测函数即可得出他属于哪一类别。-The samples are classified into positive samples, negative samples, and the samples are difficult to distinguish. The samples are labeled
