Seeing and Imagining as One: Unified Video Generation and 4D Perception for Embodied World Modeling

Read the original on arXiv Computer Vision →

The paper introduces GenSight, a unified embodied world model that combines future video generation and dense perception into a single pretrained video diffusion transformer. GenSight employs a shared spatiotemporal representation for video, depth, embodiment segmentation, and first‑frame‑relative 2D flow, and uses lightweight task modulation to predict all modalities within the same architecture. The model supports both multi‑step future video generation with aligned dense predictions and single‑step dense perception from an observed video, demonstrating strong performance on embodied manipulation data across multiple robot embodiments and human‑hand interactions.

UniDynamics: Event-RGB Fusion for Unified Future 4D Dynamic Scene Generation

UniDynamics is a diffusion-based framework that generates future 4D dynamic scenes—comprising RGB, depth, and optical flow—from a single event-RGB pair, without needing long histories or control priors. It introduces an Event Latent Enhancement module to align event data into conditioning features and a Perceptual Dynamics Space within a multi-scale U‑Net to decouple and adaptively interact depth and flow, enforcing geometric and motion constraints for coherent predictions. Experiments on VKitti2 and DSEC show state‑of‑the‑art performance, producing high‑quality, temporally coherent, and 4D‑consistent predictions even under high‑speed motion blur.

Perceive, Predict, and Plan: a Unified World Action Model for Egocentric Dexterous Manipulation

The paper introduces P³-WAM, a unified world action model for egocentric dexterous manipulation that integrates 3D perception, action-conditioned prediction, and goal-directed planning. It operates in three modes—Perceive, Predict, and Plan—using a mixture-of-transformers architecture that shares base weights and adapts to modality-specific inputs. Experiments demonstrate that unified training improves performance across all three capabilities, outperforming specialized baselines on 3D hand reconstruction and action-conditioned video prediction while producing more instruction‑adherent manipulation videos.

World-Ego Modeling for Embodied Video Generation in Long-Horizon Navigation-Manipulation Tasks

The paper introduces the World-Ego Model (WEM), which separates an embodied video into a background‐only world component and an ego component comprising the robot and manipulated objects. By using role‑conditioned attention and asymmetric query budgets for state prediction, coupled with a semantic‑routed mixture‑of‑experts diffusion generator, WEM disentangles the generation of scene evolution and instruction following. The authors also release HTEWorld, a large dataset of 125K training clips and 300 evaluation trajectories for long‑horizon navigation‑manipulation tasks, and demonstrate that WEM outperforms prior methods on this benchmark.
