    Anyone can take a photo, sure but making art via photography is incredibly complex.

    I think that’s exactly the point. Anyone can use AI, but that doesn’t make then all artists. But there is a place for AI in art, like many other tools. Same as for other tools, jusy knowing how to use them doesn’t make you an artist. Just look at all the bad Photoshop stuff everywhere. Does that mean that using Photoshop makes you a talentless hack? Or just that a lot of hacks use it to pretend they’re artists? Same for AI.

    I like that there’s a name for it. I always try to do that if possible. Division by 25? You mean multiply by 4 and divide by 100. Convert miles to km? That’s x + x/2 + x/10.

    Not sure if qualify as old geezer, you never know on the internet. I’m old for most people here, but you mention Excel, so you sound closer to my age :)






  • You seem to talk about different things when you say “visual clue”. Yes, there will be a small duration in the video where the event happens and maybe a short aftermath. That’s not a visual clue, that’s the thing you’re looking for. What all others mean by visual clue is a definite indicator that you can see when picking any random frame in the video that tells you if that frame is before or after the event. That allows you to exclude all other frames from your search, reducing your search range by half.

    A stolen bike, a broken window, your examples that trash the place or end up with a crowd of people in the area, all leave such a visual clue. At any random frame you can check if the bike is there or not, the window is broken or not, etc.

    But let’s say you have footage of the street facing CCTV and you need to find at what time the suspect left the scene (crime happened somewhere else). There’s nothing that tells you when looking at the halfway point if the suspect already passed or didn’t. You still have to look at both sides of that point in time.

    The classic example for binary search is looking for a word in a dictionary. You open it halfway and see if the words there are before or after the one you’re looking for. Then you know which half of the dictionary you need to look in next. Then you use the same method for that half and so on.

    But what if someone highlighted a word in the dictionary and you don’t know which word? Binary search is useless. You have to skim through the whole thing until you see it.
