Court Bans Use of 'AI-Enhanced' Video Evidence Because That's Not How AI Works

A judge in Washington state has blocked video evidence that’s been “AI-enhanced” from being submitted in a triple murder trial. And that’s a good thing, given the fact that too many people seem to think applying an AI filter can give them access to secret visual data.

Technically speaking AI is any effort on the part of machines to mimic living things. So computer vision for instance. This is distinct from ML and Deep Learning which use historical statistical data to train on and then forecast or simulate.

exocortex ,

“machines mimicking living things” does not mean exclusively AI. Many scientific fields are trying to mimic living things.

AI is a very hazy concept imho as it’s difficult to even define when a system is intelligent - or when a human is.

That’s not what I said.

This the technical, industry distinction between AI and things like ML and Neural networks.

“Mimicking living things” is obviously not exclusive to AI. It is exclusive to AI as compared to ML, for instance.

There is no technical, industry specification for what AI is. It’s solely and completely a marketing term. The best thing I’ve heard is that you know it’s ML if the file extension is cpp or py, and you know it’s AI if the extension is pdf or ppt.

I don’t see how “AI” is mimicking living things while neural networks are, just because neural networks are based on neurons, the living things in your head.

There’s a lot of other layers in brains that’s missing in machine learning. These models don’t form world models and somedon’t have an understanding of facts and have no means of ensuring consistency, to start with.

rdri ,

I mean if we consider just the reconstruction process used in digital photos it feels like current ai models are already very accurate and won’t be improved by much even if we made them closer to real “intelligence”.

The point is that reconstruction itself can’t reliably produce missing details, not that a “properly intelligent” mind will be any better at it than current ai.

They absolutely do contain a model of the universe which their answers must conform to. When an LLM hallucinates, it is creating a new answer which fits its internal model.

Statistical associations is not equivalent to a world model, especially because they’re neither deterministic nor even tries to prevent giving up conflicting answers. It models only use of language

lightstream ,

It models only use of language

This phrase, so casually deployed, is doing some seriously heavy lifting. Lanuage is by no means a trivial thing for a computer to meaningfully interpret, and the fact that LLMs do it so well is way more impressive than a casual observer might think.

If you look at earlier procedural attempts to interpret language programmatically, you will see that time and again, the developers get stopped in their tracks because in order to understand a sentence, you need to understand the universe - or at the least a particular corner of it. For example, given the sentence “The stolen painting was found by a tree”, you need to know what a tree is in order to interpret this correctly.

You can’t really use language unless you have a model of the universe.

Natanael ,

But it doesn’t model the actual universe, it models rumor mills

Jesus_666 ,

Your comment is a good reason why these tools have no place in the courtroom: The things you describe as imagination.

They’re image generation tools that will generate a new, unrelated image that happens to look similar to the source image. They don’t reconstruct anything and they have no understanding of what the image contains. All they know is which color the pixels in the output might probably have given the pixels in the input.

It’s no different from giving a description of a scene to an author, asking them to come up with any event that might have happened in such a location and then trying to use the resulting short story to convict someone.

rdri ,

They don’t reconstruct anything and they have no understanding of what the image contains.

With enough training they, in fact, will have some understanding. But that still leaves us with that “enhance meme” problem aka the limited resolution of the original data. There are no means to discover what exactly was hidden between visible pixels, only approximate. So yes you are correct, just described it a bit differently.

lightstream ,

they, in fact, will have some understanding

These models have spontaneously acquired a concept of things like perspective, scale and lighting, which you can argue is already an understanding of 3D space.

What they do not have (and IMO won’t ever have) is consciousness. The fact we have created machines that have understanding of the universe without consciousness is very interesting to me. It’s very illuminating on the subject of what consciousness is, by providing a new example of what it is not.

rdri ,

I think AI doesn’t need consciousness to be able to say what is on the picture, or to guess what else could specific details contain.

Gabu ,

video camera doesn’t make up video, an ai does.

What’s that even supposed to mean? Do you even know how a camera works? What about an AI?

hperrin , (edited )

Yes, I do. Cameras work by detecting light using a charged coupled device or an active pixel sensor (CMOS). Cameras essentially take a series of pictures, which makes a video. They can have camera or lens artifacts (like rolling shutter illusion or lens flare) or compression artifacts (like DCT blocks) depending on how they save the video stream, but they don’t make up data.

Generative AI video upscaling works by essentially guessing (generating) what would be there if the frame were larger. I’m using “guessing” colloquially, since it doesn’t have agency to make a guess. It uses a model that has been trained on real data. What it can’t do is show you what was actually there, just its best guess using its diffusion model. It is literally making up data. Like, that’s not an analogy, it actually is making up data.

Gabu ,

Ok, you clearly have no fucking idea what you’re talking about. No, reading a few terms on Wikipedia doesn’t count as “knowing”.
CMOS isn’t the only transducer for cameras - in fact, no one would start the explanation there. Generative AI doesn’t have to be based on diffusion. You’re clearly just repeating words you’ve seen used elsewhere - you are the AI.

hperrin , (edited )

Yes, I also mentioned CCDs. Charge Coupled Device is what that stands for. You can tell I didn’t look it up, because I originally called it a “charged coupled device” and not a “charge coupled device”. My bad, I should have checked Wikipedia.

Can you point me to a generative AI that doesn’t make up data? GANs are still generative, and generative AIs make up data.

No computer algorithm can accurately reconstruct data that was never there in the first place.

Ever.

This is an ironclad law, just like the speed of light and the acceleration of gravity. No new technology, no clever tricks, no buzzwords, no software will ever be able to do this.

Ever.

If the data was not there, anything created to fill it in is by its very nature not actually reality. This includes digital zoom, pixel interpolation, movement interpolation, and AI upscaling. It preemptively also includes any other future technology that aims to try the same thing, regardless of what it’s called.

ashok36 ,

Digital zoom is just cropping and enlarging. You’re not actually changing any of the data. There may be enhancement applied to the enlarged image afterwards but that’s a separate process.

dual_sport_dork ,
@dual_sport_dork@lemmy.world avatar

But the fact remains that digital zoom cannot create details that were invisible in the first place due to the distance from the camera to the subject. Modern implementations of digital zoom always use some manner of interpolation algorithm, even if it’s just a simple linear blur from one pixel to the next.

The problem is not in how a digital zoom works, it’s on how people think it works but doesn’t. A lot of people (i.e. [l]users, ordinary non-technical people) still labor under the impression that digital zoom somehow makes the picture “closer” to the subject and can enlarge or reveal details that were not detectable in the original photo, which is a notion we need to excise from people’s heads.

CapeWearingAeroplane ,

I 100 % agree on your primary point. I still want to point out that a detail in a 4k picture that takes up a few pixels will likely be invisible to the naked eye unless you zoom. “Digital zoom” without interpolation is literally just that: Enlarging the picture so that you can see details that take up too few pixels for you to discern them clearly at normal scaling.

KairuByte ,
@KairuByte@lemmy.dbzer0.com avatar

One little correction, digital zoom is not something that belongs on that list. It’s essentially just cropping the image. That said, “enhanced” digital zoom I agree should be on that list.

@dual_sport_dork@lemmy.world avatar

See this follow up:

lemmy.world/comment/9061929

Digital zoom makes the image bigger but without adding any detail (because it can’t). People somehow still think this will allow you to see small details that were not captured in the original image.

faintbeep ,

Also since companies are adding AI to everything, sometimes when you think you’re just doing a digital zoom you’re actually getting AI upscaling.

There was a court case not long ago where the prosecution wasn’t allowed to pinch-to-zoom evidence photos on an iPad for the jury, because the zoom algorithm creates new information that wasn’t there.

Natanael ,

There’s a specific type of digital zoom which captures multiple frames and takes advantage of motion between frames (plus inertial sensor movement data) to interpolate to get higher detail. This is rather limited because you need a lot of sharp successive frames just to get a solid 2-3x resolution with minimal extra noise.

abhibeckert , (edited )

No it doesn’t. For example you can, with compute power, for distortions introduced by camera lenses/sensors/etc and drastically increase image quality. For example this photo of pluto was taken from 7,800 miles away - click the link for a version of the image that hasn’t been resized/compressed by lemmy:

https://lemmy.world/pictrs/image/0f20e767-35f7-4335-aec4-705b264d675f.png

The unprocessed image would look nothing at all like that. There’s a lot more data in an image than you can see with the naked eye, and algorithms can extract/highlight the data. That’s obviously not what a generative ai algorithm does, those should never be used, but there are other algorithms which are appropriate.

The reality is every modern photo is heavily processed - look at this example by a wedding photographer, even with a professional camera and excellent lighting the raw image on the left (where all the camera processing features are disabled) looks like garbage compared to exactly the same photo with software processing:

https://lemmy.world/pictrs/image/f49669c1-ac77-4a74-b40f-18a24bc74cc9.png

CapeWearingAeroplane ,

No computer algorithm can accurately reconstruct data that was never there in the first place.

What you are showing is (presumably) a modified visualisation of existing data. That is: given a photo which known lighting and lens distortion, we can use math to display the data (lighting, lens distortion, and input registered by the camera) in a plethora of different ways. You can invert all the colours if you like. It’s still the same underlying data. Modifying how strongly certain hues are shown, or correcting for known distortion are just techniques to visualise the data in a clearer way.

“Generative AI” is essentially just non-predictive extrapolation based on some data set, which is a completely different ball game, as you’re essentially making a blind guess at what could be there, based on an existing data set.

ricdeh ,
@ricdeh@lemmy.world avatar

making a blind guess at what could be there, based on an existing data set.

Here’s your error. You yourself are contradicting the first part of your sentence with the last. The guess is not “blind” because the prediction is based on an existing data set . Looking at a half occluded circle with a model then reconstructing the other half is not a “blind” guess, it is a highly probable extrapolation that can be very useful, because in most situations, it will be the second half of the circle. With a certain probability, you have created new valuable data for further analysis.

UnpluggedFridge ,

But you are not reporting the underlying probability, just the guess. There is no way, then, to distinguish a bad guess from a good guess. Let’s take your example and place a fully occluded shape. Now the most probable guess could still be a full circle, but with a very low probability of being correct. Yet that guess is reported with the same confidence as your example. When you carry out this exercise for all extrapolations with full transparency of the underlying probabilities, you find yourself right back in the position the original commenter has taken. If the original data does not provide you with confidence in a particular result, the added extrapolations will not either.

CheeseNoodle ,

And then circles get convictions so even if the model did somehow start off completely unbiassed people are going to start feeding it data that weighs towards finding more circles since a prosecution will be used as a ‘success’ to feed back into the model and ‘improve’ it.

CapeWearingAeroplane ,

Looking at a half circle and guessing that the “missing part” is a full circle is as much of a blind guess as you can get. You have exactly zero evidence that there is another half circle present. The missing part could be anything, from nothing to any shape that incorporates a half circle. And you would be guessing without any evidence whatsoever as to which of those things it is. That’s blind guessing.

Extrapolating into regions without prior data with a non-predictive model is blind guessing. If it wasn’t, the model would be predictive, which generative AI is not, is not intended to be, and has not been claimed to be.

dual_sport_dork ,
@dual_sport_dork@lemmy.world avatar

None of your examples are creating new legitimate data from the whole cloth. They’re just making details that were already there visible to the naked eye. We’re not talking about taking a giant image that’s got too many pixels to fit on your display device in one go, and just focusing on a specific portion of it. That’s not the same thing as attempting to interpolate missing image data. In that case the data was there to begin with, it just wasn’t visible due to limitations of the display or the viewer’s retinas.

The original grid of pixels is all of the meaningful data that will ever be extracted from any image (or video, for that matter).

Your wedding photographer’s picture actually throws away color data in the interest of contrast and to make it more appealing to the viewer. When you fiddle with the color channels like that and see all those troughs in the histogram that make it look like a comb? Yeah, all those gaps and spikes are actually original color/contrast data that is being lost. There is less data in the touched up image than the original, technically, and if you are perverse and own a high bit depth display device (I do! I am typing this on a machine with a true 32-bit-per-pixel professional graphics workstation monitor.) you actually can state at it and see the entirety of the detail captured in the raw image before the touchups. A viewer might not think it looks great, but how it looks is irrelevant from the standpoint of data capture.

ricdeh ,
@ricdeh@lemmy.world avatar

They talked about algorithms used for correcting lens distortions with their first example. That is absolutely a valid use case and extracts new data by making certain assumptions with certain probabilities. Your newly created law of nature is just your own imagination and is not the prevalent understanding in the scientific community. No, quite the opposite, scientific practice runs exactly counter your statements.

Natanael ,

This is just smarter post processing, like better noise cancelation, error correction, interpolation, etc.

But ML tools extrapolate rather than interpolate which adds things that weren’t there

Gabu ,

By your argument, nothing is ever real, so let’s all jump on a chasm.

dual_sport_dork ,
@dual_sport_dork@lemmy.world avatar

There’s a grain of truth to that. Everything you see is filtered by the limitations of your eyes and the post-processing applied by your brain which you can’t turn off. That’s why you don’t see the blind spot on your retinas where your optic nerve joins your eyeball, for instance.

You can argue what objective reality is from within the limitations of human observation in the philosophy department, which is down the hall and to your left. That’s not what we’re talking about, here.

From a computer science standpoint you can absolutely mathematically prove the amount of data that is captured in an image and, like I said, no matter how hard you try you cannot add any more data to it that can be actually guaranteed or proven to reflect reality by blowing it up, interpolating it, or attempting to fill in patterns you (or your computer) think are there. That’s because you cannot prove, no matter how the question or its alleged solution are rephrased, that any details your algorithm adds are actually there in the real world except by taking a higher resolution/closer/better/wider spectrum image of the subject in question to compare. And at that point it’s rendered moot anyway, because you just took a higher res/closer/better/wider/etc. picture that contains the required detail, and the original (and its interpolation) are unnecessary.

ricdeh ,
@ricdeh@lemmy.world avatar

You cannot technically prove it, that’s true, but that does not invalidate the interpolated or extrapolated data, because you will be able to have a certain degree of confidence in them, be able to judge their meaningfulness with a specific probability. And that’s enough, because you are never able to 100% prove something in physical sciences. Never. Even our most reliable observations, strongest theories and most accurate measurements all have a degree of uncertainty. Even the information and quantum theories you rest your argument on are unproven and unprovable by your standards, because you cannot get to 100% confidence. So, if you find that there’s enough evidence for the science you base your understanding of reality on, then rationally and by deductive reasoning you will have to accept that the prediction of a machine learning model that extrapolates some data where the probability of validity is just as great as it is for quantum physics must be equally true.

Natanael ,

Entropy and information theory is very real, it’s embedded in quantum physics

Gabu ,

Unicorns are also real - we created them through our work in fiction.

JasonDJ ,

Well that’s a bit close minded.

Perhaps at some point we will conquer quantum mechanics enough to be able to observe particles at every place and time they have ever and will ever exist. Do that with enough particles and you’ve got a de facto time machine, albeit a read-only one.

BluesF ,

So many things we believe to be true today suggest this is not going to happen. The uncertainty principle, and the random nature of nuclear decay chief among them. The former prevents you gaining the kind of information you would need to do this, and the latter means that even if you could, it would not provide the kind of omniscience one might assume.

dual_sport_dork ,
@dual_sport_dork@lemmy.world avatar

Limits of quantum observation aside, you also could never physically store the data of the position/momentum/state of every particle in any universe within that universe, because the particles that exist in the universe are the sum total of the materials with which we could ever use to build the data storage. You’ve got yourself a chicken-and-egg scenario where the egg is 93 billion light years wide, there.

rottingleaf ,

Complexity relates nonlinearly to the amount of moving parts.

We might be able to spend an ungodly amount of energy to do that for one particle for an hour of its existence.

Being able to build a computer (in a wide sense) that can emulate in short time (less than human life) processes consistent of more energy than was spent on its creation - it’s something else.

ricdeh ,
@ricdeh@lemmy.world avatar

That’s wrong. With a degree of certainty, you will always be able to say that this data was likely there. And because existence is all about probabilities, you can expect specific interpolations to be an accurate reconstruction of the data. We do it all the time with resolution upscaling, for example. But of course, from a certain lack of information onward, the predictions become less and less reliable.

AlolanYoda ,

In my first year of university, we had a fun project to make us get used to physics. One of the projects required filming someone throwing a ball upwards, and then using the footage to get the maximum height the ball reached, and doing some simple calculations to get the initial velocity of the ball (if I recall correctly).

One of the groups that chose that project was having a discussion on a problem they were facing: the ball was clearly moving upwards on one frame, but on the very next frame it was already moving downwards. You couldn’t get the exact apex from any specific frame.

So one of the guys, bless his heart, gave a suggestion: “what if we played the (already filmed) video in slow motion… And then we filmed the video… And we put that one in slow motion as well? Maybe do that a couple of times?”

A friend of mine was in that group and he still makes fun of that moment, to this day, over 10 years later. We were studying applied physics.

Imagine a prosecution or law enforcement bureau that has trained an AI from scratch on specific stimuli to enhance and clarify grainy images. Even if they all were totally on the up-and-up (they aren’t, ACAB), training a generative AI or similar on pictures of guns, drugs, masks, etc for years will lead to internal bias. And since AI makers pretend you can’t decipher the logic (I’ve literally seen compositional/generative AI that shows its work), they’ll never realize what it’s actually doing.

So then you get innocent CCTV footage this AI “clarifies” and pattern-matches every dark blurb into a gun. Black iPhone? Maybe a pistol. Black umbrella folded up at a weird angle? Clearly a rifle. And so on. I’m sure everyone else can think of far more frightening ideas like auto-completing a face based on previously searched ones or just plain-old institutional racism bias.

Sure, no algorithm is able to extract any more information from a single photo. But how about combining detail caught in multiple frames of video? Some phones already do this kind of thing, getting multiple samples for highly zoomed photos thanks to camera shake.

Still, the problem remains that the results from a cherry-picked algorithm or outright hand-crafted pics may be presented.

Natanael ,

Depends on implementation, if done properly and if they don’t try to upscale and deblur too much then that kind of interpolation between multiple frames can be useful to extract more detail. If it’s a moving subject then this type of zoom can create false results because the algorithm can’t tell the difference and will think it’s an optical artifact. For stationary subjects and photographers it can be useful

TheBest , (edited )
@TheBest@midwest.social avatar

This actually opens an interesting debate.

Every photo you take with your phone is post processed. Saturation can be boosted, light levels adjusted, noise removed, night mode, all without you being privy as to what’s happening.

Typically people are okay with it because it makes for a better photo - but is it a true representation of the reality it tried to capture? Where is the line of the definition of an ai-enhanced photo/video?

We can currently make the judgement call that a phones camera is still a fair representation of the truth, but what about when the 4k AI-Powered Night Sight Camera does the same?

My post is more tangentially related to original article, but I’m still curious as what the common consensus is.

If I had taken a picture of two people, and then one of those people murders the other shortly afterwards, could my picture be used as evidence to show they were together just before the murder? Or would it be inadmissible because it was an AI-doctored photo?

ricecake ,

Computational photography in general gets tricky because it relies on your answer to the question “Is a photograph supposed to reflect reality, or should it reflect human perception?”

We like to think those are the same, but they’re not. Your brain only has a loose interest in reality and is much more focused on utility. Deleting the irrelevant, making important things literally bigger, enhancing contrast and color to make details stand out more.
You “see” a reconstruction of reality continuously updated by your eyes, which work fundamentally differently than a camera.

Applying different expose settings to different parts of an image, or reconstructing a video scene based on optic data captured over the entire video doesn’t capture what the sensor captured but it can come much closer to representing what the human holding the camera perceived.
Low light photography is a great illustration of this, because we see a person walk from light to dark and our brains will shamelessly remember what color their shirt was and that grass is green and update your perception, as well as using a much longer “exposure” time to capture more light data to maintain color perception in low light conditions, even though we might not have enough actual light to make those determinations without clues.

I think most people want a snapshot of what they perceived at the moment.
I like the trend of the camera capturing the image, and also storing the “plain” image. There’s also capturing the raw image data, which is basically a dump of the cameras optic sensor data. It’s basically what the automatic post processing is tweaking, and what human photographers use to correct light balance and stuff.

Great points! Thanks for expanding. I agree with your point that people most often want a recreation of what was perceived. Its going to make this whole AI enhanced eviidence even more nuanced when the tech improves.

I think the “best” possible outcome is that AI images are essentially treated as witness data, as opposed to direct evidence. (Best is meant in terms of how we treat AI enhanced images, not justice outcomes. I don’t think we should use them for such things until they’re significantly better developed, if ever)

Because the image is essentially at that point a neural networks interpretation of the image that it captured, which is functionally similar to a human testifying to what they believe they saw in an image.

I think it could have a use if used in conjunction with the original or raw image, and the network can explain what drive it’s interpretation, which is a tricky thing for a lot of neural network based systems.
That brings it much closer to how doctors are using them for imaging analysis. It doesn’t supplant the original, but points to part of it with an interpretation, and a synopsis of why it things that blob is a tumor/gun.

There’s different types of computational photography, the ones which ensures to capture enough sensor data to then interpolate in a way which accurately simulates a different camera/lighting setup are in a way “more realistic” than the ones which heavily really on complex algorithms to do stuff like deblurring. My point is essentially that the calculations done has to be founded in physics rather than in just trying to produce something artistic.

This is what I was wondering about as I read the article. At what point does the post processing on the device become too much?

Natanael ,

When it generates additional data instead of just interpolating captured data

fuzzzerd ,

What would you classify google or apple portrait mode as? It’s definitely doing something. We can probably agree, at this point it’s still a reasonably enhanced version of what was really there, but maybe a Snapchat filter that turns you into a dog is obviously too much. The question is where in that spectrum is the AI or algorithm too much?

Natanael , (edited )

It varies, there’s definitely generative pieces involved but they try to not make it blatant

If we’re talking evidence in court then it’s practically speaking more important if the photographer themselves can testify about how accurate they think it is and how well it corresponds to what they saw. Any significantly AI edited photo effectively becomes as strong evidence as a diary entry written by a person on the scene, it backs up their testimony to a certain degree by checking for the witness’ consistency over time instead of trusting it directly. The photo can lie just as much as the diary entry can, so it’s a test for credibility instead.

If you use face swap then those photos are likely nearly unusable. Editing for colors and contrast, etc, still usable. Upscaling depends entirely on what the testimony is about. Identifying a person that’s just a pixelated blob? Nope, won’t do. Same with verifying what a scene looked like, such as identifying very pixelated objects, not OK. But upscaling a clear photo which you just wanted to be larger, where the photographer can attest to who the subject is? Still usable.

Every photo you take with your phone is post processed.

Years ago, I remember looking at satellite photos of some city, and there was a rainbow colored airplane trail on one of the photos. It was explained that for a lot of satellites, they just use a black and white imaging sensor, and take 3 photos while rotating a red/green/blue filter over that sensor, then combining the images digitally into RGB data for a color image. For most things, the process worked pretty seamlessly. But for rapidly moving objects, like white airplanes, the delay between the capture of red/green/blue channel created artifacts in the image that weren’t present in the actual truth of the reality being recorded. Is that specific satellite method all that different from how modern camera sensors process color, through tiny physical RGB filters over specific subpixels?

Even with conventional photography, even analog film, there’s image artifacts that derive from how the photo is taken, rather than what is true of the subject of the photograph. Bokeh/depth of field, motion blur, rolling shutter, and physical filters change the resulting image in a way that is caused by the camera, not the appearance of the subject. Sometimes it makes for interesting artistic effects. But it isn’t truth in itself, but rather evidence of some truth, that needs to be filtered through an understanding of how the image was captured.

Like the Mitch Hedberg joke:

I think Bigfoot is blurry, that’s the problem. It’s not the photographer’s fault. Bigfoot is blurry, and that’s extra scary to me.

So yeah, at a certain point, for evidentiary proof in court, someone will need to prove some kind of chain of custody that the image being shown in court is derived from some reliable and truthful method of capturing what actually happened in a particular time and place. For the most part, it’s simple today: i took a picture with a normal camera, and I can testify that it came out of the camera like this, without any further editing. As the chain of image creation starts to include more processing between photons on the sensor and digital file being displayed on a screen or printed onto paper, we’ll need to remain mindful of the areas where that can be tripped up.

Fantasitc expansion of my thought. This is something that isn’t going to be answered with an exact scientific value but will have to decided based on our human experiences with the tech. Interesting times ahead.

The crazy part is that your brain is doing similar processing all the time too. Ever heard of the blindspot? Your brain has literally zero data there but uses “content-aware fill” to hide it from you. Or the fact, that your eyes are constantly scanning across objects and your brain is merging them into a panorama on the fly because only a small part of your field of vision has high enough fidelity. It will also create fake “frames” (look up stopped-clock illusion) for the time your eyes are moving where you should see a blur instead. There’s more stuff like this, a lot of it manifests itself in various optical illusions. So not even our own eyes capture the “truth”. And then of course the (in)accuracy of memory when trying to recall what we’ve seen, that’s an entirely different can of worms.

We can currently make the judgement call that a phones camera is still a fair representation of the truth

No you can’t. Samsung’s AI is out there now and it absolutely will add data to images and video in order to make them look better. Not just adjust an image but actually add data…on it’s own. If you take an off angle photo and then tell it to straighten it it will take your photo, re-orient, and then “make up” what should have been in the corner. It will do the same thing for video. With video it also has the ability flat out add frames in order to do the slow-motion effect or smooth out playback if the recording was janky.

Samsung has it out there now so Apple and rest of the horde will surely be quick in rolling it out.

Yeah, this is a really good call. I’m a fan of what we can do with AI, when you start looking at those upskilled videos with a magnifying glass… It’s just making s*** up that looks good.

You’d think it would be obvious you can’t submit doctored evidence and expect it to be upheld in court.

elshandra ,

If only it worked that way in practice eh.

We found these marijuanas in his pocket, they were already in evidence bags for us even.

The model that can separate the fact from fiction and falsehood will be worth far more than any model creating fiction and falsehood.
