P: Allow facial recognition feature to re-index a folder/collection

Hello, it would be really helpfull to have this fonction allowed !

Same for me. I need this function !!

At least can "reopen" all the faces where "no face" has been allocated (or it went lost as in the thousands in my case). That should not be a big deal. Keep the "indexed" faces and reopen all the rest.

The feature request to be able to re-index is on the backlog. When re-indexing, Lightroom would need to consider what to do with the existing faces and the faces found by the re-indexing. Different customers would want different options on how to combine the two.

As far as the indexing engine is concerned, we're always looking for improvement but it takes time. Adobe don't have much choice in terms of third party face SDKs that runs on Windows and Mac, and that is performant.

And regarding performance. Give us a little control over it for ourselves. I'm perfectly happy letting the indexing run "full speed" when I'm not otherwise using the computer and if it actually works.

Not sure what you guys are even talking about. Just allow to re-do face recognition on all photographs. Nothing more. And the whole issue was caused by LR6 itself, when faces recognized in the past "disappeared" AND where blocked making the whole functionality utterly useless.

Simon, I think we, the community, are looking for BETTER indexing and we are hoping that reindexing is a potential solution.

When I take multiple group photos with 10 people in them and it points to the background as faces, on a green screen no less, then something is seriously wrong with the algorithm. It figured out half the faces in some pictures, 2 in another, and 8 in yet another. There were no significant differences in the images except for people smiling/blinking/etc. which was the point of taking multiple shots. I uploaded the same photo to Facebook or and Picassa and those programs had no problem finding faces. Apple has also been doing this perfectly fine on Macs for years.

To make matters worse, I suspect more professionals use Lightroom for the bulk of their process and are looking for face recognition to help index photos for their clients.

Simon, It is good that some work is being/has been done on performance. However what those of us who have posted here are actually looking for is the ability to re-index images (which isn't possible at all) and be able to get LR to look for faces it has missed (without deleting those it has found).

Can you give us some indication of whether that issue is being looked at?

Thanks
Ian.

There were some under the hood face indexing performance improvements made in Lr CC 2015.2/6.2, especially on large Lightroom catalogs. The team did not advertise it much because of other Lr CC 2015.2/6.2 issues (which got resolved in Lr CC 2015.3/6.3).

Indexing 100K photos is some serious work. Lightroom has always try to tread a fine line between allowing you to continue to work in Lightroom while indexing is running in the background vs getting indexing work done in the shortest amount of time.

Yes, I feel kind of ripped off by Adobe, as the only reason I upgraded to LR6 was to finally have face recognition after all these years of waiting. To be honest, the implementation is a joke, and like you I find it amazing that a big player such as Adobe even bothers to roll out a half-baked product like this when Picassa have nailed it years ago.
