CascadeClassifier Training - pressing "Return" Key continues computation.
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?
this sounds very very weird, and you're the 1st person ever to report such a behaviour.
os / opencv version ? how did you install it ?
Windows 10; OpenCV 2.4.11 - 32 bit precompiled binaries. I'm mostly using negative samples that fit the training window size perfectly...
I'll create and share a dataset on monday. The behaviour doesn't always occur, but often.
well, it's definitely not the intended behaviour..
