📢📢📢 Velox 🚀: Learning Representations of 4D Geometry and Appearance

In our #CVPR2026 paper, we introduce a method for learning a native 4D representation, useful for many downstream tasks, such as video-to-4D, 3D tracking, cloth simulation, and others!

📢 Check out Lyra 2.0: large-scale generative worlds with a 3D-consistent video diffusion model. Optionally, feed-forward 3DGS and/or mesh reconstructions.

Great work by @TianchangS, @xuanchi13, and the rest of the crew. Grateful for my time with all of these brilliant people 🙏

📢📢📢Dark3R (#CVPR2026) recovers camera poses and point clouds—and enables novel view synthesis—from images captured in ultra-low light (image SNR < −4 dB).

📢 Lyra: Generative 3D Scene Reconstruction via Video Diffusion Model Self-Distillation

Got only one or a few images and wondering if recovering the 3D environment is a reconstruction or generation problem? Why not do it with a generative reconstruction model!

We show that a camera-conditioned video diffusion model can be transformed into a generative reconstruction model that directly outputs a high-quality 3D Gaussian Splatting representation through self-distillation, without requiring real-world training data.

Check out our results in the video (wait for dynamic scenes in the second half!) :

Incredibly exciting work!

[Esther Lin @estheroate]

Every lens leaves a blur signature—a hidden fingerprint in every photo.

In our new #TPAMI paper, we show how to learn it fast (5 mins of capture!) with Lens Blur Fields ✨

With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.
