这个函数,是人脸识别主函数,里面出现过的函数之一,作用是初始化分类器的数据,就是一个xml文件的数据初始化。 1staticCvHidHaarClassifierCascade* icvCreateHidHaarClassifierCascade( CvHaarClassifierCascade*cascade )2{3CvRect* ipp_features =0;//定义一个矩形框指针4float*ipp_weights =0, *ipp_thresholds =0...
我们将看到使用Haar基于特征的级联分类器进行人脸检测和眼睛检测的基础知识 我们将使用cv:: cascadecclassifier类来检测视频流中的对象。具体来说,我们将使用以下函数: cv:: cascadecclassifier::load加载.xml分类器文件。它可以是Haar或LBP分类器 cv:: cascadecclassifier::detectMultiScale执行检测。 理论 基于Haar特...
