after training you can get "cvHOGClassifier.yaml" in the genfile.
the you can load it with : hog.load("cvHOGClassifier.yaml")
here is an example:

cv::Mat gray_image;
cv::cvtColor(res_image, gray_image, cv::COLOR_BGR2GRAY);
cv::HOGDescriptor hog;  
hog.load("cvHOGClassifier.yaml");
std::vector<cv::Rect> found, found_filtered;
hog.detectMultiScale(gray_image, found, 1.3, cv::Size(2,2), cv::Size(4,4), 1.05, 10);
