RFE: crop and save (unknown) faces

[plysdyret]

Hi

I miss a feature to crop and save faces which can then be fed into the known faces structure.

Mvh.

This would be useful, but one would need to figure out how to make this happen easily from a "UX" perspective. mlapi/ES are both backend servers with no UI per se, so when an unknown face is detected, how do we "ask" the user who this is?

[plysdyret]

I suggest ignoring the UX part for now and just dump the crops the same way the boxed images are saved. Users can then look at the crop dir in the file system and copy relevant faces to the known faces directory.

Very useful and only a few lines of code needed 🙂

Mvh.

please give it a whirl See config.ini for unknown_face related changes

Great!

Pulled and enabled. For some reason persons are detected almost always but face detections are few and far between so it might take a bit before I can give any feedback.

I also have a bunch of buggy events in zoneminder since updating mlapi. They seem to be registered just fine, just no video. Seems related due to timing.

Saving unknown faces seems to work like a charm though =)

Please update all components (mlapi+ES+detection) and let me know if you still see this error

[plysdyret]

Thanks, updated. Looking good so far =)

There's this though:

" Install Hook [y/N]:y * Installing Hooks ** Checking for YoloV3 data files.... yolov3.cfg exists, no need to download yolov3_classes.txt exists, no need to download yolov3.weights exists, no need to download

Checking for TinyYOLO data files... yolov3-tiny.cfg exists, no need to download yolov3-tiny.txt exists, no need to download yolov3-tiny.weights exists, no need to download sudo: pip3: command not found ERROR:python hooks setup failed "

I know you don't like rookie questions but I can't see the problem. Pip3 is on my path.

[pliablepixels]

Maybe pip3 is not installed globally and when you do sudo it’s not found?

[plysdyret]

I seriously dislike python packaging. You were right, so I just removed the sudo part from the install script and it ran. Thanks!

Haven't seen the error with the new version.
