Despite these similarities, subtle differences emerged:

Features like chin-cheek distance, eye size, nose shape 🤥, and face-width-height ratio (especially in 3D) explained much of the variance in the human judgments.

Our results showed a strong correlation between 2D and 3D viewing conditions, indicating consistent processing of face similarity across dimensions.

However, ...

We employed a triplet odd-one-out task (🥸,🤓,😎) and distributed it online to thousands of participants.

We then trained sparse (#VICE, @lukasmut.bsky.social) and deep encoding models (#VGG-Face) to investigate the latent representations underlying human face similarity judgments.

We are happy to share our new paper (under review) on human face perception!

In this study, we investigated how face similarity judgments are affected by dynamic 3D vs. static 2D conditions 🗿.

Then, we extracted and related XAI-based relevance maps to features like gray matter volume #GMV, cortical thickness, perivascular spaces (#PVS) and fractional anisotropy #FA, a proxy of the integrity of white matter #WM tracts.

Our results? (4/7)
