Has anyone looked into image tagging and other similar features such as face recognition etc.?

I think these kind of features got a bad reputation due to privacy concerns when using centralized systems, but with HubZilla's permission system and decentralized nature it could actually be done in a privacy preserving manner.

Looks like this php-wrapper for OpenCV recently got rewritten for php7, so it might be a good candidate for use optional in Hubzilla? See:
https://www.xarg.org/project/php-facedetect/
https://github.com/infusion/PHP-Facedetect

I also found this, as maybe a simple fallback on webhosts: https://github.com/mauricesvay/php-facedetection

This phython project might be a good inspiration of what additional features could be nice in the gallery of HubZilla:
https://github.com/hooram/ownphotos-backend

By the way: is it possible to show multiple location markers the same time in an overview of a gallery?

I am really just a beginner developer, so this is probably out of my league to implement, but if someone more experienced was interested to give it a go, I would definitely try to support that effort.

P.S.: Similarly a friends location tracking & check-in system would be cool, is this: https://gitlab.com/zot/ownmapp still being developed?

I've been interested for some time in what I'll just call "skin detection" so we can collapse photos that somebody forgot to tag n-s-f-w. Existing systems a few years ago worked poorly, and learning systems unfortunately need huge amounts of training data to increase accuracy. We don't have such a large data store. I think it's interesting to be able to prove that an ethically designed distributed system can still do some "big data" types of things but we just have to draw the line firmly so there is no question of ethics.

@poVo Do you know https://pypi.python.org/pypi/face_recognition ? This is a python library. The face recognition is very CPU and RAM intensive.

I let this python library tag my photo collection automatically with the person(s) shown on the photo, see https://github.com/einervonvielen/import-faces It works well but eats MUCH CPU and RAM.
/update/ I should update the readme.doc But as you see face_recognition is quite powerful.
