- Sift patent should expire soon.
OpenMVG, OpenSfM have natively multiple alternatives to SIFT for matching.
See here for OpenMVG: https://github.com/openMVG/openMVG/blob/develop/src/software/SfM/main_ComputeFeatures.cpp#L98
We also have other method implemented but not yet connected to the SfM pipelinehttps://github.com/openMVG/openMVG/tree/develop/src/openMVG/features
As you said OpenMVG and Colmap are flexible and can ingest anything.
OpenMVG also provide a demo to integrate any OpenCV feature detector here https://github.com/openMVG/openMVG/blob/develop/src/software/SfM/main_ComputeFeatures_OpenCV.cpp#L61
Did were you thinking to other patents?

Thanks for all the interesting info. I took notice of the -m
option, but then discovered that it only accepted "SIFT".
In addition to SIFT, there's also SURF, which comes with similar restrictions.

The -m
option accepts 4 possibilities (SIFT, SIFT_ANATOMYY, AKAZE_MLDB, AKAZE_LIOP) and then you can plug any of your own feature using the abstraction that is in place.

I must have missed that. Thanks.
