Hello,
I've seen problems for the application opencv_traincascade.exe being stuck in finding enough negatives samples, so that the application stops on terminal output NEG current samples: x. I could collect more negative samples or reduce numNeg parameter, but I've observed some strange behaviour instead:
If the program is stuck in this way and I press the return-key on my keyboard, most of the time the program immediately continues with some higher "NEG current samples"-value (and often additional increases occur fast).
Can anyone explain what is happening on that keypress? Is it a bug or a feature? Is it ok to do so? Am I destroying my classifier-result or lowering its performance?
