[Feature] Merge multiple faces

[eygraber]

The feature

I recently added 10k photos/videos to my library, and each individual person has had many faces generated for them. I've been going through each face and merging them one by one into the correct face (by setting the name, not by using the merge feature), but that's been very slow and tedious.

I think it would be great if on the merge feature, I was able to select multiple other faces to merge into it. That way I could browse through the list of faces, selecting the matching ones, and then merge them all in at the end when I'm ready.

Platform

• Server
• Web
• Mobile

This is already possible. On the main people page, select 'merge faces' on an entry, and then you can select multiple faces in the list to merge into it.

Oh very cool, didn't notice that. Thanks!

I wonder, why is it limited to only up to five faces? I can imagine it could burden the server if the merged faces were linked to thousands of photos, but why not leave that up to the user and perhaps display a warning?

immich/web/src/lib/components/faces-page/merge-face-selector.svelte

Lines 58 to 64 in c6f56d9

	if (selectedPeople.length >= 5) {
	notificationController.show({
	message: 'You can only merge up to 5 faces at a time',
	type: NotificationType.Info,
	});
	return;
	}

So I managed to temporarily change it in the browser by editing the Javascript code snippet the browser downloads when you visit the merging face page. I did this in Brave, but the same approach should work in Chrome (and likely in any Chromium-based browser) as well. In case anyone reading this has the same issue, here's a guide to how I did that (tested with Immich v1.90.2):

1. navigate to the merge face page (select a person in the Explore tab, click Merge person)
2. open devtools (F12)
3. navigate to the Sources tab
4. find and open _app/immutable/nodes/18.44ecc5a4.js in the tree view on the left side (I'm not sure if the filename is static, YMMV)
5. press Ctrl + F and search for You can only
6. edit the condition surrounding the searched text (in my case if (i.length >= 5)) to whatever value you want
7. press Ctrl + S to save the changes
8. right-click the edited JS file and click Override content
9. click Select folder that showed up and choose a directory for the changed JS file (I think it's best to save it in an empty directory)
10. refresh Immich page

and then you can merge as many faces as you set.

I'm aware there are more solutions, all probably more permanent than this, but I didn't need it more than once so far.
To make the change last longer, I believe you could docker exec into the immich_server container, find the mentioned JS file and edit it there. That should (I think) last until a new Immich update.

5. press Ctrl + F and search for You can only

In the current version you need to search all files for: merge_people_limit
Mine was in: 16.aqnNSgqQ.js

This is not possible with the mobile application.

Yes I noticed it the other night that merging isn’t available on mobile. Would be great since auto loading is from our mobiles.
