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

[Wolf Eilers]

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.

Re-indexing on its own is not a lot of good unless it is changed so that it recognises the 50% of faces it ignored the first time!

It does some good if lightroom crashes and the face indexing stops halfway through and doesn't restart.

Or when people have rejected suggested face regions from a large number of photos (which has happened a lot).

Facial Recognition in LR6 is very poor. Sometimes it does not put the square over the face even in a portrait. In an example folder of 120 photos, the suggested people rectangle was towards the upper left of the photo, unrelated to where the face was, in most photos. Moving the rectangle is a painful task, I have 120,000 photos in my catalog. Sometimes, LR6 guessed correctly even if only part of the face was visible. What then, if I accept, does that mess up all future matches. If I reject, how to I get it to look for the face again. If I move the rectangle, will I live long enough to do all 120,000 photos. Please fix this soon. It is potentially a great tool. Attached is a photo with a face that LR6 could not find.

Here is another photo that had faces LR6 could not find. These faces had previously been found in other photos. I am finding that LR6 tends to put the bounding rectangle at the upper left as in this photo and the one I posted previously: In other words LR6 has no clue whether there is a picture or not. Moving the rectangle and identifying the face, did not result in improved performance on similar photos.

I've just been doing some work in Google Picasa this morning - and it really hit home just how good Google's product is (especially for a free consumer app) and how bad Adobe's implementation is. Google have an amazingly good hit rate, it's super easy & fast to remove false matches and the process has little impact on other software features when using the program. Adobe really need to the their stuff together.

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.

[FeedbackCommunityMember]

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 !

[andreasa33772134]

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.

[davidh93831741]

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.

Victoria, I think you are confusing the guess window and the confirmed window. I've got the same as David. In the confirmed panel, a single stack for each of 4 persons (with a high number of hits inside), then 15 stacks of one person (i.e. same person and same name on stack) with a low numer of hits inside each. I've tried to drag one stack on top of the other for this same name, accepting to 'rename' in the process (though it is a rename to the same name), but to no avail. Do you have any tip for this problem?

[Victoria Bampton LR Queen]

Can we try some proper names for different UI elements? That might help us all be on the same page. At the top of the People view we have Named People then below we have Unnamed People. In the Single Person view, we have the Confirmed section at the top and then the Similar section. Where are you looking? Or screenshots would help greatly.

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?

[FeedbackCommunityMember]

Completely agreed. Please include this in next update to Lightroom 6!

[ColinMcD]

This is a must. Please adobe correct this ommission

[FeedbackCommunityMember]

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.

[FeedbackCommunityMember]

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.

[FeedbackCommunityMember]

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

[FeedbackCommunityMember]

I see the inverse problem here occasionally (less than 1%) too: a face detection box that includes only a section of the background, or similar, which I have to manually delete. I've stared at several of these to try and see why Lightroom thinks there is a face there, and I just don't see it. It's like Lightroom is experiencing a strange computer version of pareidolia.

[FeedbackCommunityMember]

I just tried it, and it isn't working for me. I tried both a 360° rotation and a 90° left-then-right rotation.

I read elsewhere that this won't work if you manually delete a region that Lightroom automatically added because it sets a flag in its DB that says "I already checked that one," so it refuses to go and try again, apparently thinking it would just waste a bunch of CPU cycles doing something it has already done.

The problem with that logic is that Lightroom knows more about faces when you tell it to go and look for faces again, so it should be able to do a better job the second time around.

[FeedbackCommunityMember]

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.

[FeedbackCommunityMember]

what can I add.. please please give us the feature. I am so satisfied with LR, but this is really missing 😞
