Flow Matching Policy Gradients

ICLR 2026poster

Flow-based generative models, including diffusion models, excel at modeling continuous distributions in high-dimensional spaces. In this work, we introduce Flow Policy Optimization (FPO), a simple on-policy reinforcement learning algorithm that brings flow matching into the policy gradient framework…

LuxRemix: Lighting Decomposition and Remixing for Indoor Scenes

CVPR 2026

We present a novel approach for interactive light editing in indoor scenes from a single multi-view scene capture. Our method leverages a generative image-based light decomposition model that factorizes complex indoor scene illumination into its constituent light sources. This factorization enables

Eye, Robot: Learning to Look to Act with a BC-RL Perception-Action Loop

CoRL 2025poster

Humans do not passively observe the visual world---we actively look in order to act. Motivated by this principle, we introduce EyeRobot, a robotic system with gaze behavior that emerges from the need to complete real-world tasks. We develop a mechanical eyeball that can freely rotate to observe its…

Pippo: High-Resolution Multi-View Humans from a Single Image

CVPR 2025highlight

We present Pippo, a generative model capable of producing 1K resolution dense turnaround videos of a person from a single casually clicked photo. Pippo is a multi-view diffusion transformer and does not require any additional inputs - e.g., a fitted parametric model or camera parameters of the input…

NeRFiller: Completing Scenes via Generative 3D Inpainting

CVPR 2024poster

We propose NeRFiller an approach that completes missing portions of a 3D capture via generative 3D inpainting using off-the-shelf 2D visual generative models. Often parts of a captured 3D scene or object are missing due to mesh reconstruction failures or a lack of observations (e.g. contact regions…

Nerfbusters: Removing Ghostly Artifacts from Casually Captured NeRFs

ICCV 2023poster

Casually captured Neural Radiance Fields (NeRFs) suffer from artifacts such as floaters or flawed geometry when rendered outside the input camera trajectory. Existing evaluation protocols often do not capture these effects, since they usually only assess image quality at every 8th frame of the train…

Studying Bias in GANs through the Lens of Race

ECCV 2022poster

"In this work, we study how the performance and evaluation of generative image models are impacted by the racial composition of the datasets upon which these models are trained. By examining and controlling the racial distributions in various training datasets, we are able to observe the impacts of…

The One Where They Reconstructed 3D Humans and Environments in TV Shows

ECCV 2022poster

"TV shows depict a wide variety of human behaviors and have been studied extensively for their potential to be a rich source of data for many applications. However, the majority of the existing work focuses on 2D recognition tasks. In this paper, we make the observation that there is a certain persi…

Detecting Natural Disasters, Damage, and Incidents in the Wild

ECCV 2020poster

damage, and incidents in the wild","Responding to natural disasters, such as earthquakes, floods, and wildfires, is a laborious task performed by on-the-ground emergency responders and analysts. Social media has emerged as a low-latency data source to quickly understand disaster situations. While mo…
