It is well known in the OpenCV community that the Haar object detector, SIFT & SURF object recognition algorithms are patented.

My question if FACE RECOGNITION is patent-free and can I use it commercially?

Thanks & Kudos OpenCV!

The only patented algorithms in openCV that cannot be used for commercial use are SIFT and SURF. Even then if it is for research or projects in an academic context, you can always apply for a free license with the owners of the patent.

Haar wavelet object detector, the technique of Viola & Jones is free to use as a face detection module, even in commercial applications, as is the face recognition algorithm based on fisher or eigenfaces.

One other comment: SIFT and SURF have patents, but it a) also depends on the application you'd like to use it b) depends also on the country it applies to. So, read the patents first!

What about OpenFace?

OpenFace is not an OpenCV repository. It is an apache license, which tells you what to do with it https://github.com/cmusatyalab/openfa...
