Some time ago I had contacted the SURF developer (Herbert Bay); I report the email exchange:
Andrea paz "I would like to ask for clarification about the implementation of SURF: Speeded Up Robust Features in the FindObj plugin of OpenCV, which is used in the open source NLE software Cinelerra-GG. (https://www.cinelerra-gg.org/). Like all NLE programs, it can be used in an amateur way, but also to produce videos for commercial use. The doubt is about SURF license: is it possible to use OpenCV FindObj in Cinelerra-GG? For now an old version is implemented from which SURF has been excluded; but I was wondering if it is possible to use more updated versions that include SURF." Answer (Herbert Bay) "Sorry, don't know. That's too long time ago and I personally didn't implement SURF in Open CV.

In my opinion, if the direct supervisor is not interested, it means that he gives the green light for its use in CinGG. In your opinion, is it better not to risk it? -- Cin mailing list Cin@lists.cinelerra-gg.org https://lists.cinelerra-gg.org/mailman/listinfo/cin
