I will present our work related to color constancy and color assimilation illusions at #ACCV24 in Oral Session 5 at 09.00 and afterwards in Poster Session 3 at 15.20. 👋👋

We introduce the first strategy that allows us to solve two computationally opposing phenomena with a single method! 🥳🥳

Here is the #IllusionOfTheDay! 🌤️

Take a closer look at the letters in ACCV and HANOI.

We see the letters as if they are different, but all the letters in ACCV and HANOI are the same within themselves!

P.S. ACCV is just around the corner! Less than two weeks until the conference! 🚀

Another #IllusionOfTheDay to brighten your day! 🌤️

Take a look at these two clouds.
One appears blueish, while the other looks yellowish.

But here’s the twist: their actual reflectance values are identical! 🤯

Remove the context, and you’ll see their colors are exactly the same.

Amazing, right? 🧠

Here is the #IllusionOfTheDay to brighten your day on Bluesky! 🌈

You might see "Blue" as yellow,
And "Sky!" as blue.

But what is true?
"Blue" is blue,
And "Sky!" is green! 🤯

It’s all about your brain,
And the context of the scene. 🧠

Let's look at these triangles!

Here's another color illusion to brighten your day on Bluesky! 🦋

All the triangles have identical reflectance, but we perceive them as if they have different colors! 🌈

P.S.
@bsky.app, please bring a custom GIF option so I can animate these illusions! 🙏😁

Baklava in the Clouds"

I present you another color illusion to brighten your day! 🌈

The 2 clouds and 2 diamond-shaped "Baklavas" have identical reflectance within themselves, but they appear different to our eyes due to their context! 🤯

What color do you see the Baklavas? 🤔

#IllusionOfTheDay

Another fascinating color illusion to brighten your day on Bluesky! 🌈

Although the "Snake" has the same reflectance throughout the image, we perceive it with different colors. 🤯🤯

If only @bsky.app allowed custom GIFs, I could animate this and really show how context "fools" us! 🫤
#IllusionOfTheDay

Color constancy & illusions show how our visual system 'moves.' By understanding how we process colors, we can gain insight into the whole brain (Zeki, 1993).

As part of the computer vision community, we should explore their link to create simple, effective algorithms that mimic human perception.
