Is there yet a way to delete one person?

Two of my sons have all gotten grouped under one of their names. I know that ultimately, I need to readjust the matching settings. For the most part, matching has been great, and I have over 500 people in my DB. So, I don't want to start over - I want to delete the one name (one of my sons) and then re-id the "missing" faces and hopefully get them both correct. Is there a way to do this?

not easily, you would need to use the API to move the "incorrect" faces to a new person. I can't think of a better way to do it

I don't mind if it's not easy, I'd just like to fix it.

So, I have to boys - Ari and Max.

Most of the young Ari pictures are labelled Max, in addition to all the young Max pictures.

The older pictures of both are often correct.

There are a lot of these - over 1000. It would take a very long time to correct manually.

So, ideally, I would delete "Max" from the entire DB. Then I would rematch all the missing faces with higher sensitivity.

Is this along the lines of what you were thinking using the API?

there's no easy way I'm afraid. The API alternative suggested was more of an option if you are willing to script something, but with that many assets, it may be difficult.
one possible, destructive way, would be to tamper with the DB and remove the person, that should also remove all the faces associated with it.

if you decide to go this route, make sure you:

stop immich_server container (to avoid any change)
take a backup of the current DB.
execute the following in your DB
```
DELETE FROM person where id = 'THE_PERSON_ID';
```
```
DELETE FROM person where id = 'THE_PERSON_ID';
```
(you can get the person ID going to the people tab, and choosing the person in question, the id is the string of numbers and leters in the URL /people/b8e41-5474-400c-83af-4170ec1859
start immich_server and launch the face detection job... you may want to reduce the Maximum recognition distance setting first, to avoid getting the same results

I think I'll try this.

How would you change these settings?

NoMachine•7/10/25, 3:18 PM

I would lower it to 0.3

NoMachine•7/10/25, 3:19 PM

if the same person is detected as 2 different people, is very easy to fix. the other way around (your case), is not

NNoMachine I would lower it to 0.3

volcs0OP•7/10/25, 3:23 PM

Also - and sorry for the noob question - I start the entire stack from a single compose file.

So, it sounds I need to do a docker compose down for just the server - and then docker exec into the DB container to complete this?

NoMachine•7/10/25, 3:31 PM

no, just

docker stop immich_server

docker stop immich_server

NNoMachine no, just `docker stop immich_server`

volcs0OP•7/10/25, 3:45 PM

OK did this and removed the person from the DB.
I decreased the maximum recognition distance to 0.3

When I clicked "Missing" in "Face Detection" in jobs, it showed a count of "1" and then zero.

I clicked on "Missing" in "Facial Recognition" and it is showing 200,000 (and counting down).

Is this right?

NoMachine•7/10/25, 3:47 PM

check the logs if faces are being detected

It's going quickly

NNoMachine check the logs if faces are being detected

volcs0OP•7/10/25, 4:37 PM

When I click "refresh" or "missing" in face detection, nothing happens. And there is nothing in the log. Shouldn't refresh kick off a rescan of every picture for faces?
Clicking "missing" for facial recognition does kick off a full scan

NoMachine•7/10/25, 4:41 PM

did it create the new persons?

volcs0OP•7/10/25, 5:00 PM

I'm going through it now. I see faces waiting to be named now - which I I guess that I want.

volcs0OP•7/10/25, 5:01 PM

I was just surprised that when I clicked "refresh" under "face detection" nothing happened. But maybe all the faces were detected, and it's the recognition step that's important (the clustering)

darkthunder1432•7/11/25, 7:02 AM

Yes, face detection means just get picture and detect bounding boxes for each person. even if we delete person from database these bounding boxes don't change.

face recognition is the step which takes this picture with bounding box and clusters face.

volcs0OP•7/11/25, 2:45 PM

This process worked. I deleted my three sons - since they were a mess. And now I'm going back and re-adding them. With the distance set to 0.3, they are really split up, but I'm getting there.

Is there yet a way to delete one person?
