2013-07-04 20:36:37 -0600 | commented answer | Required leaf false alarm rate achieved. Branch training terminated. I have changed the parameter numStages to 20, but the result is not what I want either. The command and logs are as follows: command: opencv_traincascade -data haarcascade -vec samples.vec -bg negatives.dat -numPos 10 -numNeg 3000 -numStages 20 -w 20 -h 20 -minHitRate 0.99 -maxFalseAlarmRate 0.5 -mode ALL logs: maxWeakCount: 100 mode: ALL Stages 0-1 are loaded ===== TRAINING 2-stage ===== <BEGIN POS count : consumed 10 : 17 NEG count : acceptanceRatio 3000 : 1.12322e-06 Required leaf false alarm rate achieved. Branch training terminated. The frustrating thing is I have not run command opencv_traincascade successfully. Could you give me a runnable example? |

2013-05-28 20:14:52 -0600 | asked a question | Required leaf false alarm rate achieved. Branch training terminated. I use these commands:
negative images are from http://tutorial-haartraining.googlecode.com/svn/trunk/ object image is the result is ===== TRAINING 1-stage ===== POS count : consumed 10 : 10 NEG count : acceptanceRatio 3000 : 0.000429487 Required leaf false alarm rate achieved. Branch training terminated. now, I have no idea how to resolve this problem, need help. answers from stevenputtemans
I follow point 2 and use command "opencv_traincascade -data haarcascade -vec samples.vec -bg negatives.dat -numPos 10 -numNeg 3000 -numStages 2 -w 20 -h 20 -minHitRate 0.99 -maxFalseAlarmRate 0.5 -mode ALL", but the result is "Required leaf false alarm rate achieved. Branch training terminated." too. As for point 3, without createsamples tool, how should I create sample.vec file? |
