Lightroom 6: Three Face Recognition Issues

I just purchased LR6 last night and had fun with the face tagging feature. Some parts worked reasonably well, others not so much.1) LR should assume that a person is only in a photo once. I got lots of group photos where LR was suggesting that the same person was in a photo more than one time. Even after I confirmed one of the suggestions, the other suggestion would remain. This problem was exacerbated for me because I have a lot of photos of my identical twins. But the problem existed for other people as well. The recognition algorithm should assume that a person is only in a photo once. Only the match with the highest score for a given name should be accepted. Once a person has been confirmed in a photo, that person should not be suggested as any other person. If the end user wants to manually add a person twice (for all of those photos of people looking in a mirror?) then LR should allow that.2) Stacking suggestions is rather hit-or-miss. I won't address the general quality of the feature here, but one particular problem. As I tag faces in a given folder the recognition engine seems to continue to use that new data to reanalyze the suggestions it has made, that is all well and good, but I have noticed a number of times where LR reevaluates the photos in a stack and makes new suggestions for some of the photos, but doesn't then pull them out of the stack. Then when you click on the stack separator to confirm that these 6 faces are really the same person, you discover that 2 of them have suggestions as a different person. As soon as the suggestions change, the images should be pulled out of the stack.3) The sorting doesn't update quickly enough. I leave on the default sorting that sorts the faces by suggestions. As the recognition engine reevaluates many images that had suggestions change to become question marks. That becomes a problem when you want to confirm a large set by shift-clicking, but now there is an inaccurate question mark in the middle of the dozen suggestions you want to confirm. This is just a nuisance, but since that reevaluation is so constant, it would be great if the window sorting were updated more often.Thanks for a fun and useful feature. I look forward to seeing performance improvements in updates.-

 LR should assume that a person is only in a photo once. This would be a small but bug steps in improving face recondition.

Hi,

Thanks for reporting this issue. If possible can you share some sample photos to reproduce the issue?


Thanks,

I have found a sample photo to where Lightroom suggests the same name for two individuals in the photo. Do to the sensitivity of the photos though I would like to not post them on a public forum. Do you have a contact email that I could send them too?

I am the original poster. I don't immediately have a sample photo for the issue of having someone tagged multiple times in one photo, but I do have an example of my second point. In the attached image you can see a "stack" that has been identified, but the recognition engine has identified each photo in the stack as a different person. That stack should immediately break down if the images are no longer recognized as the same person.

OK, I'm going to post two more examples. One is another example of the stacking problem. This time there is a three photo stack that shows two of them as one person, one as another (in this case my twin sons, and it does identify them properly). The second one is a group photo where you can see that it has identified Josiah Reedy in the photo twice.

Here's one more really obvious one of a person showing up twice in one photo. In this case it is my twins, and one of the guesses is correct.

Hi, while sorting photos tonight I had one example where LR would be totally wrong at finding a face ! The lower face rectangle was drawn by LR when searching for faces. Can this also be fixed ?

PS: You can contact me to have the original photo.
