问题
I am trying to create a haar cascade for hand detection and no matter what I do, I can't seem to get it finished. It always seems to end up stuck in some loop. I read a suggestion online that suggests to add code into the loop that will save the current working image into a temporary location. This solution would at least give me a place to start troubleshooting, but my problem here is my lack of C++ which OpenCV is written in. So if anyone can give me a suggestion of how to go about implementing this, that would be much appreciated.
