Hello all,

I am currently using the opencv_traincascade application to train a cascade classifier. I have read that it is possible to pause the program (and even use the intermediate result). How should I go about doing this? Can I just kill the program (ctrl+c)? And how do I continue where I left off later?

I just want to make sure I don't lose all of my data- it has been training for well over a day so far.

Thanks in advance.

If you ctrl-c the program it will stop, leaving behind the partial xml files in the directory you specified. To continue with the training later, just run the traincascade with IDENTICAL parameters (don't change pictures either). It will continue on from the latest xml file. Partial stages will be re-evaluated.

As mentioned the only downside to this is loosing the last stage that was calculating, and since time increases exponentially, this will be a big chunk of the training time.
