Showerthoughts
What if we treat a long audio file's spectrogram as one "optical 2D map"? Then use a DeepEncoder style model (deepseek-OCR) to compress that entire "image" into just ~256 vision tokens.a decoder could then try to decompress those tokens back into the full transcript & speaker labels.🫠

I think this comment could provide a similar insight into the illusion in our example. Beyond that, I don't have any further comments at this time. If anything comes to your mind, don't hesitate to share the knowledge 😁

comment from the paper: "The reason is that the black/white contrast signals between adjacent dots along the length of the line are stronger than black/grey or white/grey contrast signals across the line, and the motion is computed as a vector sum of local contrast-weighted motion signals"

well I just discovered this illusion, and it doesn't really resemble the other illusions I've experiment 🙃. The one it most resembles is the following:

bsky.app/profile/altu...

You are right, but when there is no "movement", the effect—at least in my perception—seems quite weak :-)
Also, a bit to test what you said: When I increased the bg brightness, this time I definitely needed the motion now...😁

included some post-processing etc, to polish it, but still need to look at full-screen. seems not a strong effect.

I was reading this book over the weekend. Until I got to this page "Motion Perception in the Human Vision". I stopped reading the book and tried to code the illusion 😁
