Assertion Failed during opencv_createsamples
I am trying to create a vec file from my positive image samples. I'm using the latest version of Opencv. The command I am using is this:
opencv_createsamples -info Positive.info -num 3750 -w 24 -h 24 -vec Positive.vec
All my images are bigger than 24x24, so I don't believe that that is the issue. I've tried searching online, but I don't find anyone with this error while doing the createsamples command. The output that I get when I run that is this:
Info file name: Positive.info
Img file name: (NULL)
Vec file name: Positive.vec
BG file name: (NULL)
Num: 3750
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: 24
Height: 24
Max Scale: -1
RNG Seed: 12345
Create training samples from images collection...
OpenCV: terminate handler is called! The last OpenCV error is:
OpenCV(4.0.0-alpha) Error: Assertion failed (0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows) in cv::Mat::Mat, file c:\build\master_winpack-build-win64-vc15\opencv\modules\core\src\matrix.cpp, line 465
This is my first time using opencv, so I'm very unclear as to what this error is. Anyone have any experience with this or can point me in the right direction to correcting the error?
Edit: Here is the first few lines of my Positive.info file:

The path to the files is correct.
please show the first few lines of your
Positive.info@berak Updated.
please don't use backslashes there, but forward ones, even on windows.
i can only guess here, but it's one of:
@berak Could you explain what you mean by "bounding box does not fit". I will try the other things you suggested. Thank you.
the error complains about a roi out of bounds, right ?
so the resp. Mat was either empty, or too small
also have a look at the src code, recompiling it with
CV_VERBOSEdefined will output a lot of informationalso (if it's within your skills), simply try to debug it ....
I'll take a look. Thanks.
have a look here
(that's where your assert is coming from. so either src empty() or roi too large.)
and again, the way the filename is parsed there: NO single backslashes (use 2 of them or forwar ones) or spaces in the filename allowed !
I'll be looking at this later today, and I'll try those things.
I have the same problem too. Could you please help me. I dont understand how ı can solve this problem from your comments. could you please give me detail to solve this error
