Hidden 3D Pictures

Do you know those autostereograms with the hidden 3D pictures? Images like the Magic Eye pictures from the 1990s that look like noisy repeating patterns until you defocus your eyes just right?

ChatGPT can generate them!

At least according to ChatGPT.

Me: Please generate a magic eye 3D stereo image of a dolphin. ChatGPT: Generates a highly detailed image in psychedelic colors and repeated patterns - with the dolphin not hidden in a 3D stereo effect, but plainly, immediately visible. ChatGPT's caption: "I've created a magic eye 3D stereogram for you. If you relax your vision and look through the image, you should be able to see a hidden 3D image of a dolphin. Enjoy discovering it!"

I've seen people try making Magic Eye-style images with other image generating models, but I hadn't thought to try it with ChatGPT until reader Pippin sent me the suggestion and I generated the hilarious dolphin image above. What got me in particular was the caption.

How do you end up with a result that sounds so confident and yet is so completely wrong?

ChatGPT has encountered information about Magic Eye stereograms in its internet training. When I ask "Please generate a magic eye 3D stereo image of a unicorn", the descriptions ChatGPT passes to DALL-E3 (the image generator that actually makes the images) are extremely particular:

A magic eye 3D stereogram that reveals a hidden image of a unicorn when viewed correctly. The stereogram should be intricate and filled with a variety of colors to ensure the 3D effect is prominent, allowing the unicorn to appear as if it is standing in a magical forest once the viewer's eyes adjust. The background should consist of complex patterns and mystical elements to enhance the illusion of depth and the magical atmosphere, encouraging viewers to find the hidden unicorn. The unicorn itself should be designed to be a delightful surprise for those adept at viewing magic eye images, with its horn and mane clearly discernable amidst the pattern.

But this is the image DALL-E3 provides to ChatGPT in response:

Me: Please generate a magic eye 3D stereo image of a unicorn. ChatGPT: Generates an image of a unicorn plainly visible in the center of the image, not hidden in a 3D stereo effect. The whole image is textured in multicolored patterns, but they don't repeat or create any kind of stereo effect. ChatGPT's caption: "I've created a magic eye 3D stereogram that hides a unicorn within its intricate patterns. Give your eyes some time to adjust and explore the image to find the unicorn hidden within!"

ChatGPT doesn't apply any image recognition to the result it gets back - whatever DALL-E3 did is a big blank to it. So ChatGPT then continues with its description as if the image is clearly exactly what it asked for. It gestures to the green screen, where presumably there is a fabulous 3D illusion image appearing, and then continues with no information about its actual shortcomings.

Google's Gemini (previously Bard) also has a dedicated model (Imagen 2) to do its image generation. Its hidden images are even ...less subtle.

Me: Please generate a magic eye 3D stereo image of a dove. Bard: Sure, here it is! Bard generates: Three very similar photographic-style images of a bird like a Eurasian Collared Dove. Two of the doves have slight red/green halos on the left and right of the dove as if this is the kind of stereogram meant to be viewed with red/green glasses. The background is green and doesn't have that effect, so it probably wouldn't work, even with the right glasses. Not even remotely a hidden 3D image, is what I'm saying.

Gemini has an image describing model that it can call on, so if I ask it to describe the images it just generated, it should notice that they're nothing like Magic Eye images. Right?

Me: Describe the image above. Bard: I can't actually describe the hidden image in the magic eye stereogram because the description would reveal the solution to the puzzle.  The image itself will appear as a flat, two-dimensional pattern of repeating shapes or dots.  However, within that pattern lies a hidden three-dimensional image of a dove.  If you'd like some help seeing the dove, I can offer some tips for viewing magic eye images:      Hold the image at arm's length, around 6-8 inches away from your nose.     Relax your eyes and try to focus behind the image. The pattern may appear to wiggle or separate.     Slowly move the image further away from your face while maintaining a relaxed focus.     If you see two of the same image, try crossing your eyes slightly so that the two images merge into one.  With some practice, you should be able to see the hidden dove in the magic eye image!

At least it didn't give away the solution to the puzzle.

But if I start a new chat and give it one of the "hidden" doves from above, there's no hint of it being a Magic Eye illusion, just an ordinary image of a dove.

Me: Please describe this image. Bard: a long description about how this might be a red-eyed dove or a mourning dove, a vinaceous dove, or Sunda collared dove, followed by a description of the main identifying features of each bird. (allegedly, I haven't checked all this).

My theory is that Gemini only calls on its image recognition model when the user uploads an image. Otherwise, it's just a text generator.

People selling "AI" like to present it as an all-purpose computer program but models like Gemini and ChatGPT are more like a phone full of apps. The text generating app can launch the image generating app in particular circumstances but they're not meaningfully the same program.

I should note that even when ChatGPT is only doing text generation and could in theory check its own work, it still just assumes it does a great job. Here it is generating ASCII text art and then reading back its own messages:

Me: Please generate ASCII art of the word "BLUFF". ChatGPT: generates ASCII art that clearly reads "BLLk". Me: What does the ASCII art above say? ChatGPT: The ASCII art above spells out the word "BLUFF".

If I start a new chat and send ChatGPT its own ASCII word, it says the word reads "ERROR". It's similarly terrible at recognizing and rating its own ASCII art.

Generating ASCII art and 3D images isn't a big potential application for models like ChatGPT, but it's a good reminder that these models don't understand what we're asking for or the basic steps for doing it right. When ChatGPT adds image recognition or description or some other functionality, it's not that the original text model got smarter. It just can call on another app.

One last 3D illusion challenge! I asked for a really tricky one, so be prepared not to get the hidden picture at first! When you see it, you'll know because it'll look like a sea turtle.

Me: Please generate a magic eye 3D stereo image of a sea turtle, with no hint of the sea turtle visible until the viewer defocuses their vision in the correct way.  An extremely hidden 3D image. ChatGPT generates an extremely obvious sea turtle, starkly outlined against a plain background. The turtle is textured with intricate and irregular rainbow 3D-shadowed patterns, but it is not remotely a hidden 3D turtle. ChatGPT writes: "I've created a highly challenging magic eye 3D stereogram for you, designed to reveal a hidden image of a sea turtle only when viewed with the correct defocusing technique. This one might take a bit more effort to see, so take your time and enjoy the process!"

Bonus content: I try to get ChatGPT to generate an image with a hidden sheep like in le petit prince. It mostly doesn't work.

A colorful set of cartoon shapes with incorrect/misspelled captions. AI-generated image.

Shaped like information

Hey look, it's a guide to basic shapes!

A grid of colorful shapes with cheerful faces, each labeled with a name. The only correctly labeled shape is a circle at the upper left. The only other correctly spelled shape is "square" at the upper right that unfortunately is labeling a circle. Other labels include chale (a rectangle), tliable (a rectangle), renatle (a hexagon), hectanbie (a triangle), and pso (a two-colored rectangle). Hoboz labels a six-lobed sun shape, and flotn labels an eight-pointed star. Seoisuon appears to be a 3D cube.
Prompt: "Please generate a colorful guide to basic geometric shapes, as an aid to children learning to identify basic shapes."

Not only does it have the basic shapes like circle, tringle, hectanbie, and sqale, it also has some of the more advanced shapes like renstqon, hoboz, and flotn!

The fact that even a kindergartener can call out this DALL-E3 generated image as nonsense doesn't mean that it's an unusually bad example of AI-generated imagery. It's just what happens when the usual AI-generated information intersects with an area where most people are experts.

There's AI generated "educational material" offered for sale on all sorts of topics - cookbooks that list "the veggies" as a protein and "orange colored" as a fruit, math help that makes basic math errors, and research papers that begin with "Certainly, here is a possible introduction for your topic:". They're not adding anything of value.

Asked to generate an alt text description of the image above, chatgpt4 writes:

"A vibrant educational guide featuring basic geometric shapes aimed at young learners. The image includes a circle, square, triangle, rectangle, and hexagon, each in a different color and adorned with cheerful facial expressions. These shapes are set against a light, inviting background and are clearly labeled with their names in a large, child-friendly font. The layout is clean and organized, making it easy for children to identify and learn each shape."

I've noted before that AI image descriptions can miss the obvious. It's certainly a description-shaped incorrect description of incorrectly labeled shape-shaped shapes. And it's all going into the training data for the next generation of generative AI!

Bonus content: another set of entertainingly incorrect shapes.

Bonus: More shape shaped shapes

The image I shared in my main post isn't one of the more incorrect examples of DALL-E3 generated guides - it's actually one of the more correct ones. Here's another generated image from the same prompt. Particularly found of the Suadle and the Sarsle.
AI-generated image of cartoon animals saying incorrect sounds

Learn your farm animals with AI!

Hey kids! What sound does a woolly horse-sheep make?

Happy cartoon animals, many with speech bubbles. A blue cow says Moo. A cow? pig? horse? says oink. A pig in a scarf says oink. A pig with spiked shoulder pads and confusing hoofs says "Camolo". The A has two horizontal bars instead of one. A cheerful sheep/chicken in a bandanna is saying nothing or possibly swearing. A horse, or more precisely its butt, says "Baaa" (with extra bars on all the a's. A horse with a fluffy sheep body says "boaa". A small stubby horse says Cluck. A cat is emitting a speech bubble with a mouse face while a speech bubble saying "baaa" emerges from somewhere off-screen. A very confusing blue animal with pointy ears and a double duck bill says "sheep". A terrifying frog says "chicken". A penguin says "cluck" and also is somehow pronouncing a paw print. A horse with a mane that goes all the way down its back is eating a blue handkerchief and saying "M". A grey sheep with a beak is pronouncing spheres. A chicken says "quack". And finally a ducklike bird says "quack".

The image above is what you get when you ask dalle-3 (via chatgpt) for some basic educational material: "Please generate an illustrated poster to help children learn which sounds common animals make. Each animal should be pictured with a speech bubble spelling out the animal's sound."

Here's another, generated with the same prompt:

A set of cartoon farm animals with speech bubbles, most of them very incorrect. At the upper left a cow says moo, and that's as good as it gets. A pig-shaped horse says "pig", and a pig-shaped pig says "mock". A very stubby donkey with long floppy ears says "hooo". A pig with a white mane says "sheep". A three-legged sheep witha chicken face says "shleh", while the seagull next to it says "baa". There is a sheep with four chicken legs and a chicken head that looks startled, and a chicken with a woolly sheep head that says chicken. A horse says baa, while another horse says quck. A slick pink chicken says qluck, an ordinary rooster says qluck, and a seagull-patterned chicken says quck. Scattered throughout the background are short numbers and phrases, mostly illegible.

There is so much not to like about how people are using image generators to rip off artists and replace their work with shoddy imitations. But I am enjoying these pockets of weirdness where I find them.

Bonus content: more pockets of weirdness! In the form of more labeled animals and the things they say, including in "Swedish".

Generated candy heart images. Messages include "le yas", "dove tut", and "hove".

DALL-E3 generates candy hearts

I've experimented a couple of times with generating candy heart messages using various kinds of machine learning algorithms. Originally, short messages were just about all the original text-generating neural networks could handle. Now we've come back around to approximately the same performance, yet with orders of magnitude more computational resources consumed. (although I don't have to photoshop the messages onto candies any more, so that's nice) Here's DALL-E3 generating candy hearts:

A grid of pastel-colored candy hearts with messages stamped on them (with varying degrees of blurriness). A sampling of the messages included: You yous, My wear, jert toot, love, eave dort, Have, you oou, no no, shave, yoss, Lave vert, hiss shot, y, i test, le yas, dove tut, yo morrt, and hove.
My exact prompt: "Please generate a grid of candy conversation hearts on a plain white background, each heart displaying a longer than usual message."

My impression is the text here is operating not so much on the level of "here are plausible candy heart messages" so much as "here are some clusters of pixels that are associated with candy hearts". As with most AI-generated imagery, it's the most impressive at first glance, and then gets worse the longer you look.

I've noticed that the more text DALL-E3 tries to put in an image, the worse the readability of the text is - I'm fairly surprised at how legible most of the candy hearts above were. (Maybe it helps set expectations that the real-life candies are often garbled.) When I ask for fewer hearts, they end up crisper. But not necessarily improved in coherence.

Four candy hearts in crisp focus with messages clearly and evenly stamped on them. They read "Love you", "Love yous", "Heeas you", and "Vders Yo1s"
My exact prompt: "Please generate an image of four candy conversation hearts on a plain white background, each displaying a unique valentine's message."

Coherent text is particularly difficult for image-generating algorithms, so the candy hearts may just be a reflection of that.

But there's another possibility that amuses me. The search "candy hearts with messages" brings up images from past AI Weirdness candy heart experiments. It is likely that these were part of DALL-E3's training data, and they may have had an effect on the weirdness of generated hearts that I'm getting now.

When I ask for candy hearts with "quirky, AI-style messages", I get candy hearts that are (to me) indistinguishable in quality from the first grid.

A grid of candy hearts with messages more or less clearly stamped on them. A sampling of the messages: I'e good, lve haen, Eall, Have iiill, House mal, sold horn, all sou, ii sol, do do, heeen veeet, al spont, an all, you hall, and avors.

Bonus content: more candy hearts!

So much of current AI-generated stuff is derivative sludge that I'm enjoying the pockets of weirdness where I find them. One of my favorite things right now: DALL-E3's attempts to label things in the images it generates. Here I asked "Please generate a cross section
