Only empty vec files

Which version of OpenCV are you using?

[luckk93]

Opencv 2.4.8

I'm sorry to say, I don't have any idea. This looks good to me. The only thing I can recommend is reading through the remarks of the original author of opencv_createsamples.pl

Try setting right chmod to samples folder.

Also this one liner is easier to use: perl bin/createsamples.pl positives.txt negatives.txt samples 1700 "opencv_createsamples -bgcolor 0 -bgthresh 0 -maxxangle 1.1 -maxyangle 1.1 maxzangle 0.5 -maxidev 40 -w 24 -h 24"

Hello, I’m trying to follow your tutorial to create Haar cascade Training Files but at the step 5, it create 19 .vec files, but their are all empty (0 byte) so the step 6 fail.
I have 20 positive photos and 100 negative photos, all with 4160 x 2340 pixels, so my -w and -h are 128 and 72 (same ratio). All the steps have been done on a linux virtual machine.

I hope you can help my find the problem.

The command:

perl bin/createsamples.pl positives.txt negatives.txt samples 400  "opencv_createsamples -bgcolor 0 -bgthresh 0 -maxxangle 1.1\
  -maxyangle 1.1 maxzangle 0.5 -maxidev 40 -w 128 -h 72"

The log:
