我刚开始学习opencv。我正在尝试创建训练样本，它说出创新样本已停止工作。任何帮助将完全赞赏。谢谢！
这是我写的和得到的：
c:\10X\newtest>C:\opencv\opencv\build\x86\vc12\bin\opencv_createsamples.exe -info positives.dat -bg negatives.dat -vec cropped.vec -num 2560 -w 48 -h 48
Info file name: positives.dat
Img file name: (NULL)
Vec file name: cropped.vec
BG file name: negatives.dat
Num: 2560
BG color: 0
BG threshold: 80
Invert: FALSE
Max intensity deviation: 40
Max x angle: 1.1
Max y angle: 1.1
Max z angle: 0.5
Show samples: FALSE
Original image will be scaled to:
Width: $backgroundWidth / 48
Height: $backgroundHeight / 48
Create training samples from images collection...
