SUMMARY I hope you soon will add the support for "Scan for Faces" in video files. If so, do you have an ETA on that? Thanks. STEPS TO REPRODUCE 1. Import video files 2. Scan for Faces 3. No faces are detected (It works with picture files, so it is turned on) OBSERVED RESULT Does not find faces in video files EXPECTED RESULT Some faces in "People" should show up for me to name. SOFTWARE/OS VERSIONS Windows: 10 ADDITIONAL INFORMATION Hope you will add this as I hope to get away from Google Photos solution next coming months/years...
Not a dev, but there is a project to improve the whole face recognition process in digikam. However, I have not heard anything about recognizing people in videos, so I wouldn't be optimistic about it, at least in short-medium term. Probably some of the developers will be able to give you a more specific answer.
A quick response from me : Video face detection will be time consuming. You need to read frame by frame (in critical case) to check if a face exist in image. So the video need to be decompressed and analyzed. Second point, we need a temporal property to add in database to localize a face in a specific frame from a video. This kind of value do not exist yet in database. Anyway, detection and recognition algorithm do not needs to be adjusted for video as media is analyzed by frames (images). Gilles Caulier
Real-time face detection and recognition on video are possible. However, if you wish to extract all the faces appear in the video, it is possible that too many faces are returned, depend on the number of frames. If you wish to return only distinct faces in the video, face clustering is needed. In both ways, video analyse like this, as Gilles said, is time-consuming. But if this feature is still in need, I could try to implement it
About time. I don't see problem with it. I can run it at night. But I see another problem with shouldn't be done before: to see similar faces as one with some coefficient.
