I'm trying to make a .vec file for using to create my cascade training XML file. While trying to run the code, I see an error and I couldn't find any answer about this.
May you help me, please?
The error is like that:
Unable to open image: pozitif1.jpg OpenCV Error: Unknown error code -9 () in cvSetImageROI, file C:\build\master_winpack-build-win64-vc14\opencv\modules\core\src\array.cpp, line 3021
