--- Comment #32 from Michael Moore <stuporg...@gmail.com> --- > [Mike] The number of thumbnails shouldn't go up. Is this behavior > repeatable? In other words, if you restart digikam will the number of > thumbnails go back down to 500854, or will it start at 501006? The number of thumbnails remains at whatever it was when Digikam quit. Scrolling to unconfirmed faces I haven't looked at yet continues to generate new thumbnails. Revisting previously viewed faces uses the existing thumbnail as expected. > [Mike] If you're willing to try very unstable code, grab the latest AppImage > and let's see if we can reproduce the issue.

I have disabled unchecked both "Use ExifTool backend to read metadata from files" and "Delegate to ExifTool backend al loperations to write metadata to files". I have also unchecked "Remove obsolete core database objects". The performance is much better, not nearly as fast as album view, but better than it was. As for the thumbnail generation, I'm not 100% sure what to expect. > [Mike] I can tell you with certainty that in the 8.6.0 pipelines the > thumbnail is written to the DB when it is first extracted from the original > image during face detection. > [Maik] Incorporating the creation of thumbnails in the face scan process is > also not a good idea, because we might then create the thumbnails twice. These two statements seem to contradict each other. It sounds like Mike is saying that thumbnails are supposed to be generated during first face detection, and Maik is saying that we shouldn't (and don't) do this. In any case, I guess that faces which are already detected won't have thumbnails automatically generated. If thumbnails are in fact supposed to be generated somewhere in the detection process, how can I test it and report back here? Do I need to do the Maintenance item "Reset and clear all faces and training" and then scan them again to test if they are generated at some point after detection? Maybe a new Maintenance item could be helpful under "Rebuild Thumbnails" titled "Build missing face thumbnails" or "Rebuild face thumbnails". -- You are receiving this mail because: You are watching all bug changes.
