Hi All,
I have a collection of 1947 positive images, and 2279 negative images stored in proper structure. I run the opencv_createsamples.exe successfully and it generated a file "positives.vec". When I then ran the opencv_traincascade.exe, it ran for a while, output some info (please see below) and then crashed without any useful information.
Please help!
Any help or pointer is highly appreciated.
Thanks,
Tuc
