License Questions

[maryanpetruk]

Hello @sarlinpe , @Dawars

I would like to ask what are the license of the methods listed in the hloc?
In particular for Supported local feature extractors and feature matchers.
For example, for superpoint_max, superpoint_inloc, superpoint_aachen, NN-superpoint.

I see that the license of hloc is Apache License Version 2.0 as shown in https://github.com/cvg/Hierarchical-Localization?tab=Apache-2.0-1-ov-file, but what about the internal methods and algorithms? Are those under the same license?

Thank you and I am looking forward to your reply.
