Stable Diffusion and ControlNet: “Hidden” Text (see thumbnail vs. full image)

The user is using the ControlNet model: <a href="https:&#x2F;&#x2F;huggingface.co&#x2F;monster-labs&#x2F;control_v1p_sd15_qrcode_monster" rel="nofollow noreferrer">https:&#x2F;&#x2F;huggingface.co&#x2F;monster-labs&#x2F;control_v1p_sd15_qrcode_...</a><p>I&#x27;m so happy someone has actually trained a QRcode ControlNet model so we can generate cool QRcodes, the previous methods were pretty bad and didn&#x27;t reach the quality of the images produced by that random guy who made them originally (without sharing details about how the ControlNet model was trained).

Between this and the QR code thing, AI really shines at making images that have patterns but look natural. Honestly some of the coolest uses i have seen of AI image generation.

I feel like I&#x27;m missing something given the comments here and on reddit. Do people really not see the text in the enlarged image? (Even enlarging extra) A few are a tad less clear but nothing is unreadable. I&#x27;d be extremely impressed if people were not able to read Rio, Istanbul, or London. Is there some collective unspoken agreement going on, am I just an outlier, or am I not uncommon and just no one is commenting?

I think this is exploiting image resizing algorithms, which are inaccurate because no matter how much better anyone should know, they never do the math in linear-light space so it always gets bright areas wrong.<p>Every Photoshop filter does this wrong too.

Off-topic, but did anyone else find the broken back button super annoying?

This is super fascinating - the effect worked seamlessly for me, not visible when the images are large but clear enough once they&#x27;re far away&#x2F;I squint&#x2F;zoom far out. My husband on the other hand could see the text constantly, if he could see the image at all he could see the text. Worth noting that he has some pretty serious glasses and it&#x27;s been a while since he last had his vision checked, he needs another trip soon. Fascinating.

As a hobbyist artist, and way before stable diffusion was a thing, back in 2014 (I think?) I made a similar illusion where only it can be read by looking at the thumbnail or squinting your eyes!<p>&gt;<a href="https:&#x2F;&#x2F;tamim.io&#x2F;random_shares&#x2F;thumbnail_illusion_tamimi.jpg" rel="nofollow noreferrer">https:&#x2F;&#x2F;tamim.io&#x2F;random_shares&#x2F;thumbnail_illusion_tamimi.jpg</a><p>Can you read it!?

I can easily see the text on the iphone14promax after enlarging, but it seems from the comments that some can&#x27;t.<p>Is this an optical illusion situation or a blue&#x2F;gold dress?

PSA: if you have bad eyesight, you see everything a little bit blurred all the time, so the effect won&#x27;t work well (or at all) on you.
