A autumnal stump, covered in mushrooms. This is a still from the interactive 3D reconstruction!
I’ve released a new version of my 3D reconstruction tool, Brush 🖌️ It's a big step forward - the quality & speed now match gsplat, and there’s a lot of other new features! See the release notes github.com/ArthurBrusse...
Some of the new features:
Physics with Veo! #veo2
Prompt: One ball is in the floor. Another ball comes rolling.

Information in observed images that predicts what should be in unobserved regions should be captured by these models (e.g. x.com/DotCSV/statu...). They can't create new information, but there are often more statistical hints than we as humans perceive (like the paper you linked).

A common question nowadays: Which is better, diffusion or flow matching? 🤔
Our answer: They’re two sides of the same coin. We wrote a blog post to show how diffusion models and Gaussian flow matching are equivalent. That’s great: It means you can use them interchangeably.
eh, perception as probabilistic inference is a well established theory of the mind

This is the essence of visual perception. We don't see pixels, we experience the world behind an image. Our aim is to build AI systems that can achieve this same level of spatial intelligence.
Inferring the whole from fragments requires statistical priors for both humans and machines.
unlike most work on image/video editing that is not guaranteed to "follow rules" of 3D consistency, our work builds an explicit virtual world that you can move a virtual camera through. we use a statistical learning-based system, but we distill it into a 3D model that follows at least some 3D rules

Check out CAT4D: our new paper that turns (text, sparse images, videos) => (dynamic 3D scenes)!
I can't get over how cool the interactive demo is.
Try it out for yourself on the project page: cat-4d.github.io
Stop watching videos, start interacting with worlds.
Stoked to share CAT4D, our new method for turning videos into dynamic 3D scenes that you can move through in real-time!
