I am sorry if this has been asked a million times before but I have read OpenCv is free to use for commercial use but then in the files there are cascades that ask you to contact various people if using commercially. Is there a definitive answer which i can then quote/use.
I am brand new and completing my first indie project, want to keep cost to a minimum because may never see any income (hope not) but at the same time I don't want to use something without permission.
