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

  • (Edited)
Currently it is not possible to invoke a re-indexing of facial recognition data at either the global or folder/collection level. For my purposes re-indexing at the folder and collection level would be sufficient.

Reason: when a face is removed from a previously indexed image it is not possible to automatically recognize faces other than reviewing many images and manually applying a face region.

With Picasa, I gave it a photo of my adult daughter and it looked in my 30,000 photos at that time and found a baby picture of that same daughter and matched them. Maybe an accident but there were other baby pictures and other adults. It is possible. Adobe just released the feature prematurely. I called customer service and the technician basically agreed that it is a work in process.

I absolutely love this feature but rescanning for faces MUST be possible. It is so basic.
I should be able to rescan the entire catalog or just select a few photos and have LR scan only those whether they have been previously scanned or not.

I fully agree with you. This feature have to be considered as a beta, it miss too many faces and even a lot of obvious faces that a simple compact camera can detect. Other software such as Picasa, iPhoto or Aperture (the software i used before LR6 and which has not evolved for 2 years) have a far more success ratio !

Yes, we need the possibility to re-index (or for LR6 to "re-scan") all selected photographs for faces that have not already been indexed.

Same as many, somehow a few k of indexed faces just "disappeared" for now reason, and cannot go photo by photo and manually select the face. The capability of the software is there, Adobe just need to unblock it.

I see that i'm not alone with this problem.
Hope Adobe can hear us and add new functionnalityies for the next update (or upgrade) :

- Re-indexing
- add granularity level of faces recognition (décrassé the 30% or 40% of missing faces)

Just upgraded from LR4 to LR6(CC). I've been playing with the facial recognition feature, and I have many of the same comments as above. Wow, I'm surprised Adobe released it in this state. The feature is at best at alpha quality. I guess I'll wait for the next version to be released before using this feature. I was hoping to use this feature for tagging people. I'll have to just go back to doing it manually. :( Very unfortunate. I kind of want my money back. LR4 was working fine for me.

Yes, I feel a bit duped with this upgrade. $99 to get Facial recognition (my only reason for the upgrade), which is a buggy test version that I've had to disable. Great for Adobe's profits, not so good for customers.

This thread has been running 3 months and there have been LR6 updates but I do not see any improvements in face recognition. Is anybody at Adobe monitoring this discussion and are there any plans to fix it - soon?

Definitely need this feature. If Picassa can do it, it should be in Lightroom too. The ability to tweak the detection settings on rescan (also available in Picassa) would be even more beneficial.

When I activated face recognition, I had selected a smart collection. Now only the images in this collection are face-recognised, nothing else, although I selected the option that my complete library should be indexed.

Please introduce folder re-indexing, with destroying any existing face recognition data. Perhaps" additional indexing" is more accurate than re-indexing from scratch? The ability to re add faces which have been removed would be great

Good point. I have cases where the facial recognition does not find all the faces that are obviously in the picture in which case "additional indexing" captures my need. However, I have many more cases where the facial recognition is so screwed up that only complete re-indexing is appropriate. Again, this re-indexing should be on selected folders or photos only. This thread is 6 months old. I don't see anything in new updates addressing re-indexing.

Sadly facial recognition works better in facebook than in lightroom.

Agree completely, I've been using Picasa for years and finally moved to Lightroom when I heard this feature was enabled. I have around 10k photos and I am having to go through them almost one by one.

Picasa nailed this years ago, and in local client processing rather than being web-enabled like facebook - what is wrong with Adobe?!

In the meanwhile this thread has been running 7 (!) months and there is neither a fix nor any comment or hope from Adobe. One of the major features for an upgrade from LR5 to LR6 is simply useless. For me LR6 feels like a bluff package and I'm very sad about Adobe's behaviour.

This reply was created from a merged topic originally titled I cannot rerun face detection on selected photos in Lightroom CC!!!.

When I accidently deleted some face regions it's imposible to run process on selected photos again.

In a comment above, Tomáš Houška wrote, "Additionally, I would welcome better selection management based on facial recognition. I currently cannot select 6 people and see only photo where they are all together."

You can do that with the Library Filter bar. Open the Metadata browser and add six Keyword columns:

Then select the 6 keywords, one keyword per column.

Just signed up to a years subscription to LR and PS after previously managing 100k photo collection in Picassa. i believed i was joining the leadIng edge company in the photo management field - but my experience so far with the face recognition function has been far from satisfactory. Three days of lagging computer and ridiculous matches! How can Adobe be so far behind a free resource like Picassa in this (admittedly) small, but important area of the process.

from researching the net i have found that my experience is pretty typical and this has brought me to this site and this thread. To make it worse it would seem that no one at Adobe can even be bothered to address the issue here after 9 months of complaints!

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.

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.

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.

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.

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.

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.

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.

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.
