2016-10-11 04:20:23 -0600 | asked a question | Cascade classifier detect multi scale always returns nothing. Hi guys, sorry to bother again. But when I run the the detectMultiScale on a trained cascade classifier nothing is ever detect, no rectangles. Weird thing is even with just one stage i get good results using LBP here is my results. and this is how i call the classifier ... Any hint on why this is happening? Thanks |

2016-10-07 04:10:43 -0600 | commented answer | opencv_traincascade always halts on stage 4.i Yeah trouble was exactly that my pos neg ratio was not the recommended. And some samples did not have the path correct, you are right. Now it is working, and it is on stage 7 ... yay. Thanks for the reply. |

I have 7358 of negative samples. where i list their relative path in the negative_samples file, and I have 17600 positive samples in the positives.vec file. opencv_traincascade -data cascade -vec samples/positives.vec -bg negative_samples -numStages 20 -precalcValBufSize 10 -precalcIdxBufSize 200 -acceptanceRatioBreakValue 0.0001 -w 50 -h 50 -mode ALL -maxWeakCount 100 -maxDepth 1 -weightTrimRate 0.95 |
