Diffusion Knows Transparency: Repurposing Video Diffusion for Transparent Object Depth and Normal Estimation

ICRA 2026poster

Transparent objects remain notoriously hard for perception systems: refraction, reflection and transmission break the assumptions behind stereo, ToF and purely discriminative monocular depth, causing holes and temporally unstable estimates. Our key observation is that modern video diffusion models a…

Ψ0Ψ0\Psi_0: An Open Foundation Model Towards Universal Humanoid Loco-Manipulation

RSS 2026poster

We introduce Ψ₀ (Psi-Zero), an open foundation model to address challenging humanoid loco-manipulation tasks. While existing approaches often attempt to address this fundamental problem by co-training on large and diverse human and humanoid data, we argue that this strategy is suboptimal due to the …
