[visionlist] Color assimilation with faces - there's an App for that

[Karl Gegenfurtner]

Dear all,

Some of you might have seen the demo Doris Braun and I gave
at VSS demo night 2024, and at ECVP 2025 illusion night. 

We took a portrait photo and overlaid thin stripes that made the
face appear in the color of the stripes. The Munker illusion
with faces. Back then that involved a lot of fiddling with Matlab,
but now the whole process is available as a simple app that can
be downloaded from the App store.

You can create your own Munkerized face in seconds!
And of course it is free.

Here’s a link to a short description:

and here’s the link to the App store:

It will be available on Google Play for Android in a week or two:

Enjoy!

Best wishes,

Karl
