I trained a cascade classifier to detect cars. I have 415 positive samples and 544 negative samples. After I trained the classifier, I got cascade.xml. When I use it in my program, the program will stuck when execute detectMultiScale function. But if I used trained classifier by others, there is no problem. I compare the xml file, there are some difference. I don't know whether the problem is caused by the version of xml file.
Dose any one have some idea?
