There's definitely value in providing this functionality for photographs taken in the present.
But I think the real value -- and this is definitely in Google's favor -- is providing this functionality for photos you have taken in the past.
I have probably 30K+ photos in Google Photos that capture moments from the past 15 years. There are quite a lot of them where I've taken multiple shots of the same scene in quick succession, and it would be fairly straightforward for Google to detect such groupings and apply the technique to produce synthesized pictures that are better than the originals. It already does something similar for photo collages and "best in a series of rapid shots." They surface without my having to do anything.
- thesuavefactor 3y agoEvery picture is a picture from the past though
- jawns 3y agoPhilosophically, yes. But some photo-editing techniques rely on data that is not backfillable and must be recorded at capture time. And even in cases where there is no functional impediment to applying it against historical photos, sometimes there is product gatekeeping to contend with.
- royaltheartist 3y agoOh yeah, what about this old Kodak I found in my grandpa's attic that prints pictures showing how people are going to die?
- chii 3y agobut how did you know it wasnt a coincidence that the picture depicted a similar scene in the past?
- parineum 3y agoHere's a picture of me in the future.
- miohtama 3y agoJohn Titor, is that you?
- ortusdux 3y agoNo, it's Mitch Hedberg.
- thejazzman 3y agoI had an ant farm. They didn't grow shit!
- drewbeck 3y agoWhere you get that camera at??
- ekianjo 3y agoNot the pictures where you age people artificially
- makapuf 3y agoEvery existing pictures are.
- positus 3y agoIf it hasn't been taken/made/captured yet, it isn't a picture. It's just the potential for one.
- amelius 3y agoEvery state machine is bound to cycle at some point, even if it has the size of the universe.
- flanked-evergl 3y agoThis is not true, its very trivial to design a state machine that won't cycle.
- amelius 3y agoSorry, forgot to add that it should be reversible, like the laws of physics.
- flanked-evergl 3y agoAlso, not all laws of physics are time reversible, i.e. the second law of thermodynamics.
- flanked-evergl 3y agoI would really like to see the proof that it's impossible to design a reversible state machine that won't cycle. But even if you do prove that, you would also have to prove that if the laws of physics are reversible that the universe is reversible. The current best theory and understanding of the evolution of the universe is that it will reach maximum entropy (heat death). There is no cycling when this happens. Can you cite what theory or new discovery you have come across that somehow challenges the heat death hypothesis?
- BoppreH 3y agoThat's exactly why I've been keeping all "duplicates" in my photo collections. They do take up a lot of space, and just today I asked in photo.stackexchange for backup compression techniques that can exploit inter-image similarities: https://photo.stackexchange.com/questions/132609/backup-compression-that-takes-into-account-similarities-between-images https://photo.stackexchange.com/questions/132609/backup-comp...
- syntaxfree 3y agoSuggestion: stack the images vertically or horizontally. Frequency spectrum compression schemes like JPG will see the similarity in the fine details.
- bayesianbot 3y agoI got really good compression using this technique with JPEG XL, I'm sure there's even a good reason why it works so well but it's been a long time and I don't seem to remember why.
- bondarchuk 3y ago>in the fine details Could it be possible that jpg also exploits the repetition at the wavelength of the width of a single picture, so to say? E.g. 4 pictures side-by-side with the same black dot in the center, can all 4 dots be encoded with a single sine wave (simplifying a lot here..) that has peaks at each dot?
- randyrand 3y agomost duplicates are from the same vantage point. these are not. i.e. you don't need to keep them all.
- beagle3 3y agoThose have been used for denouncing and super resolution for 30 years now - they are not useless. And storage is cheap, just keep them all.
- fenomas 3y ago> ..fairly straightforward for Google to detect such groupings and apply the technique to produce synthesized pictures that are better than the originals. Wouldn't an operation like this require some kind of fine-tuning? Or do diffusion models have a way of using images as context, the way one would provide context to an LLM?
- sangnoir 3y agoI think simpler algorithms (e.g. image histograms) can get you a long way. Regardless of the mechanism, Google Photos already has the capability to detect similar images, which is used to generate animated gifs.
