OpenCV Invalid background description file

Question

When I try using this Command: opencv_createsamples -img image.jpg -bg bg.txt -info /info/info.lst -pngoutput info -num 2600 it tells me: Invalid background descrip

Answer 1

I had the exact same problem. I tried changing the bg.txt encoding and it made no difference. I deleted all instances of OpenCV on my Ubuntu server and rebooted. I typed:

git clone https://github.com/Itseez/opencv.git

into the terminal.

Once downloaded, rebooted the server and proceeded with:

opencv_createsamples -img image.jpg -bg bg.txt -info /info/info.lst -pngoutput info -num 1500

That seemed to fix my "Invalid background description file" error.

Bear in mind that I tried to create a new folder and add a fresh download of OpenCV to use on a separate project and it just copied my existing file.

Delete all instances of the OpenCV folder before rebooting and redownloading it!
