How do I test the classifier once it has been compiled as per the steps mentioned in the tutorial?

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);
