Is SURF algorithm used in OPENCV patented? Can it be included in commercial product?


Summary:


1.SURF is not free.BRISK or FREAK is good alternative. Thanks to Notas!


2.SURF patent holder: http://www.kooaba.com/en/plans_and_pricing/ip_licensing Thanks to Steven Puttemans!


3.Only 2 nonfree module is patented: SIFT & SURF Thanks to Steven Puttemans again!


Hi, Notas & Steven, I will buy you an impressive Chinese meal when you come to Beijing! Welcome~

Yes it is patented, that's why it's in the nonfree module. To use it commercially, you have to contact the patent holders.

To be honest, I don't understand why everyone still uses SIFT/SURF when there are better alternatives in OpenCV (BRISK or FREAK for example).

Thank you very much! Would you please help on the following 2 questions: 1) Is there a list for me to contact with patent holders involved in OpenCV? 2) How can I identify free & non-free module?

http://docs.opencv.org/modules/nonfree/doc/nonfree.html Is this the answer to my 2nd question? Only 2 non-free modules in OpenCV?

For contacting the SURF owners, go to this website : http://www.kooaba.com/en/plans_and_pricing/ip_licensing. And yes, only the nonfree module is patented, all the other functionality can be used.

Is this still in effect? The reason I ask is because in the beta, there isn't any non-free module? So would the application of these algorithms commercially be permitted now?
