There are two applications in OpenCV to train cascade classifier: opencv_haartraining and

opencv_traincascade. opencv_traincascade is a newer version, written in C++ in accordance to

OpenCV 2.x API. But the main difference between this two applications is that opencv_traincascade

are integer in contrast to Haar features, so both training and detection with LBP are several times

training: the quality of training dataset first of all and training parameters too. It's possible to
