Sto usando opencv_haartraining
per la prima volta, utilizzando OpenCV 2.3.1 su Mac OS X Lion.OpenCV 2.3.1: come dire se haartraining è bloccato o ancora lavorando (sull'esempio TINY)
Sto provando ad allenare un esempio molto rapido. Sto usando solo 23 esempi positivi e 45 esempi negativi. Eppure opencv_haartraining
ha utilizzato il 100% di un core del mio Macbook Air 2010 per almeno 30 ore!
Qui ci sono i file rilevanti:
- La directory http://stanford.edu/~jonr1/haartraining_test_1/
- Il file vec di campioni positivi http://stanford.edu/~jonr1/haartraining_test_1/vec_positive_samples/vec_positive_samples.vec
- BG (negativo) Esempi http://stanford.edu/~jonr1/haartraining_test_1/bg_negative_examples.txt
- I risultati intermedi hanno prodotto finora http://stanford.edu/~jonr1/haartraining_test_1/results/
Il file vec è stato prodotto seguendo questo tutorial http://note.sonots.com/SciSoftware/haartraining.html, utilizzando il programma che l'autore mergevec
per unire i file vec prodotte individualmente da createsamples
.
L'uscita del opencv_haartraining era:

Tutto di questa uscita è stato prodotto nei primi 5 minuti della corsa. Dopo aver prodotto questa uscita, ha continuato a funzionare con il 100% di un core per 30 ore (finora) senza ulteriore output.
La mia domanda è: come faccio a sapere se haartraining si è schiantato in questo caso particolare, e più in generale, qualcuno sa come modificare cvhaartraining.cpp
in modo da emettere periodicamente lo stato? Grazie mille!
(Domande correlate, sia senza risposte:
)
Sembra che mi sia appeso. Ho usato opencv_haartraining su ~ 1000 positivo, ~ 1000 negativo e ci vuole solo un giorno. Ma non ucciderlo ancora, farò dei test sulla mia macchina Linux e ti risponderò su questo. –
Già ucciso, mi dispiace (ero preoccupato per la temperatura che stavo sottoponendo anche alla batteria del mio Macbook e mi ero logorato il ventilatore). Ma lo eseguirò sullo stesso o su dati simili in modo che possiamo avere un processo a cui collegarci. – AlcubierreDrive
Hai avuto più fortuna con la tua seconda manche? –
