How to train cascade using opencv

Question

I want to train my own cascade. At tutorial they say to use opencv_createsamples and

opencv_traincascade command.

However I cant use that commands.

My opencv folder:

opencv>> apps >> annotation      
         build   createsamples            
         cmake   traincascade  
           .     visualisation
           .     CMakeLists.txt  
           .     interactive-calibration  
                 version

My opencv version is 4.1.1

How can I do this?

did you try createsamples instead of opencv_createsamples, as your ls command shows? — Micka, Aug 16 '20 at 09:47

With newer versions of OpenCV they do not include the cascade training binaries anymore (because opencv tries to get rid of the old C code). You will have to use an older version if you want it to work. Cascade classifiers trained with older opencv version binaries should still be usable with the latest opencv lib for object detection.
