opencv traincascade错误？

Question

我使用以下参数运行了traincascade

traincascade -data haarcascade -vec samples.vec -bg negatives.dat -nstages 20 -minhitrate 0.999 
-maxfalsealarm 0.5 -npos 1000 -nneg 2000 -precalcValBufSize 1024 
-precalcIdxBufSize 1024  -w 20 -h 20 -featureType LBP -mode ALL

但我得到以下输出：

PARAMETERS:
cascadeDirName: haarcascade
vecFileName: samples.vec
bgFileName: negatives.dat
numPos: 2000
numNeg: 1000
numStages: 20
precalcValBufSize[Mb] : 1024
precalcIdxBufSize[Mb] : 1024
stageType: BOOST
featureType: LBP
sampleWidth: 20
sampleHeight: 20
boostType: GAB
minHitRate: 0.995
maxFalseAlarmRate: 0.5
weightTrimRate: 0.95
maxDepth: 1
maxWeakCount: 100

任何人都知道为什么会这样？

使用此命令

traincascade -data haarcascade -vec samples.vec -bg negatives.dat -numStages 20 -minHitRate 0.999 -maxFalseAlarm 0.5 -numPos 1000 -numNeg 2000 -precalcValBufSize 1024 
-precalcIdxBufSize 1024  -w 20 -h 20 -featureType LBP -mode ALL
