Error “Train dataset for temp stage can not be filled.” while using traincascade tool of OpenCV

Question

I\'m building the opencv_traincascade.exe tool from source code (OpenCV 2.4.0) using vs2010 on windows 7. I want to train a LBP classifier, so I\'m using opencv_traincascade

Answer 1

I am also learning how to use OpenCV object detection tools.

I noticed that if the bg file (in your case "D:\OpenCV\Classifiers\lbpclassifier1\temp\negative\infofile.txt") has a wrong format or contains a entry with non-existent file, opencv_traincascade produces error.

Hope it helps.
