Revision history [back]

Hi there,

as I finished creating my info.txt file containg the absolute paths to the images and the rectangle information of my desired objects to be detected, I just ran

opencv_createsamples.exe -info C:\Software\training\file.txt -vec C:\Software\training\samples.vec -w 20 -h 20

Unfortunaley I get an error code -9, saying:

OpenCV Error: Unknown error code -9 () in cvSetImageROI, file C:\build\master_winpack-build-win64-vc14\opencv\modules\core\src\array.cpp, line 3021

Anyone knows what's that about? Further it says it's not able to open my image, which is in a .jpg format.

I'd be glad about some help. As always, the documentation of opencv doesn't give me any hint about what to do.

Anyone knows what's that about? Further it says it's not able to open my image, which is in a .jpg format.format. The funny thing is, that the specified location (C:\build\master_winpack-build-win64-vc14....) doesn't even exist. Not even in the opencv-folder. So is this a mess by opencv (like bad handling of paths)?
