hello all, i want to asking some question about opencv using terminal
i make some sample using 'opencv_createsamples' with this code above. (bgr3000.txt contains 3000 and more negative mages)
> PC:/media/pandailing/Local Disk/PYTHON_OPENCV_VIDEO/script$ opencv_createsamples -img 1.JPG -bg bgr3000.txt -info info/info.lst -maxxangle 1 -maxyangle 1 -maxzangle 1 -num 1500
and i get this output at my terminal:
Info file name: info/info.lst
Img file name: 1.JPG
Vec file name: (NULL)
BG file name: bgr3000.txt
Num: 1500
BG color: 0
BG threshold: 80
Invert: FALSE
Max intensity deviation: 40
Max x angle: 1
Max y angle: 1
Max z angle: 1
Show samples: FALSE
Width: 24
Height: 24
Create test samples from single image applying distortions...
Done
and then, i continue to make my vector file using the code above
-PC:/media/pandailing/Local Disk/PYTHON_OPENCV_VIDEO/script$ opencv_createsamples -info info/info.lst -num 1500 -w 20 -h 20 -vec pos.vec
and get this output:
Info file name: info/info.lst
Img file name: (NULL)
Vec file name: pos.vec
BG file name: (NULL)
Num: 1500
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
Width: 20
Height: 20
Create training samples from images collection...
Done. Created 1500 samples
but when i try to traincascade using this script:
PC:/media/pandailing/Local Disk/PYTHON_OPENCV_VIDEO/script$ opencv_traincascade -data data -vec pos.vec -bg bgr3000.txt -numpos 1000 -numneg 800 -numStages 10 -w 20 -h 20
i got this error

what is wrong with my code? please help
