Instead of starting at 0 % and progressing to 100 % it seems to start at 100 % and progress to 0 %. <br></div><div>If this is to be a progress bar, it should probably be reversed. If it instead is meant as "this many items in the queue to be processed" then it should probably be shown as that somehow.

These processes run for a very long time. Thus, it would be really helpful if they did not influence the UI while running. <br></div><div><br></div><div><br></div><div>Regarding #3: I am also hosting my photo collection on a NAS (samba share) and using DK on a Win10 client. I have the digikam database, thumbnail database, etc. stored locally on my C:-drive. I think this works OK. Can't you do the same in order to fix your problem? Or am I missing something?</div><div><br></div><div>I would also be very interested in some guidelines regarding #5.</div><div><br></div><div><br></div><div>I have some more points here:</div><div><br></div><div><br></div><div>(continuing numbering from previous list)</div><div><br></div><div>6: When going through Unconfirmed faces the UI is a bit confusing: there seems to be two buttons that does the exact same judging by the help text/mouse hover hint text. These buttons are seen in the screenshot here. The red X in the upper right cornor and the "minus button" at the bottom right. Both say: "If this is not a face, click to reject it". <br></div><div>I think it is confusing that there are two buttons that does the same with very different symbols. Also I am in doubt: Do they actually do the same?</div><div>If so, I think one should be left out. Also I am really missing an operation here. The operation I am missing a button for is this: Lets say that DK detected a face. This face is just some random person in the crowd of a concert or something. This is not a person I know or am interested in tagging. I do not want to "train" DK's ML model that it is not a face, so clicking "this is not a face" would be wrong. Because it IS a face. I just want to *ignore* this face as unintesting. <br></div><div>I could, of course, create a person called UNKNOWN or John Doe or something like that and tag all faces like this as this pseudo-person. However, this is probably not a good idea, because then I will train DK's ML that this is actually a person that has many different faces. And I guess this will screw the ML up over time so that it will start to recognize a whole bunch of people as this unknown person.<br></div><div><div><img src="cid:ii_kgph8ka40" alt="image.png" width="330" height="224"><br></div><div><br></div><div>7: Another thing regarding the screenshot above. What does the minus button in the upper left corner do? In my version of DK, it does not seem to have any textual hint when hovering.</div><div><br></div><div>8: When tagging/confirming faces, it is a bit cumbersome to actually verify the face detection because you have to hover each image to see who DK detected it as. Instead, I think it should show the name directly on each face. This is almost the only relevant information to show except for the actual face image. I mean, stuff like file name, date, image resolution, size, etc. are much less important when doing face detection. <br></div><div><br></div><div><br></div><div>9: I have noticed that for some people I may only have a single photo or two of them. In these cases DK seems to find a LOT of spurious matches on these persons. Maybe this is something that could be tuned?</div><div><br></div><div>10: In my photo collection, I have photos of my children and other family members from back when they were babies and some of them are adult now. So I have *many* photos of the same persons in very different ages. However, DK seems to be confused by this. For example, when I have tagged a person as when they were baby, suddenly a lot of other babies become matched to this person. Is there any fix for this?</div><div><br></div><div><br></div><div><br></div></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Den søn. 25. okt. 2020 kl. 08.01 skrev <<a href="mailto:bryan@gillson.net" target="_blank">bryan@gillson.net</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US"><div><p class="MsoNormal">A few comments and questions on 7.2 beta and face detection:<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><ol style="margin-top:0in" type="1" start="1"><li style="margin-left:0in">I’m still suffering from occasional crashes, though they are more intermittent than 7.1. I know the Digikam team is already tracking these down as a priority, but let me know if logs would help.<u></u><u></u></li><li style="margin-left:0in">A suggestion for a UX change: After face detection, I multiselect thumbnails and confirm “unconfirmed” faces and manually tag others. Selecting the proper name causes the selected thumbnails to disappear, then reappear, then disappear (one at a time) as they’re processed. This shifts the remaining thumbnails around, making it difficult to multiselect another set of faces without error. I would prefer that faces “in process” simply stay hidden after selecting the name, and only appears again in the appropriate category (either “Confirmed” or in the proper People tag). This way I could continue “queueing up” new faces to process while KD works on the others.<u></u><u></u></li><li style="margin-left:0in">The face recognition workflow on a NAS-based setup really reinforces the need to separate thumbs.db into a local database. Performance is abysmal when refreshing thumbnails, and makes working over even a gigabit LAN very frustrating. Bug 297299 (<a href="https://bugs.kde.org/show_bug.cgi?id=297922" target="_blank">https://bugs.kde.org/show_bug.cgi?id=297922</a>) covers this feature request. Is it in the plan to address this?<u></u><u></u></li><li style="margin-left:0in">While on the topic of performance, are any bottlenecks being investigated to increase speed when using a network DB (MariaDB)? Neither CPU, network, database, nor disk statistics show high use during the recognition process. I would expect the database and network to be getting hit hard when retrieving pictures, then seeing the RAM and CPU spike during recognition. Instead, everything just goes at a trickle.<u></u><u></u></li><li style="margin-left:0in">Finally, is there any documentation on how to optimize the Detection process? What is more effective: confirming faces in the Unconfirmed tag? Correcting incorrectly recognized faces in a specific People tag? Adding new pics to known faces that are in Unknown, to better train the AI? Is it better to tag many samples of a person’s face, or a few? How frequently should I re-run “Recognize faces” after adding/correcting/confirming faces? Given the significant time investment in tagging and recognizing, guidance on the above could save dozens of hours of effort.<u></u><u></u></li></ol><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">I love Digikam, and truly appreciate all the effort.
