BinoGen: Scaling egocentric binocular data for embodied visual perception and learning

Read the original on arXiv Computer Vision →

BinoGen is an automated framework that generates large-scale, embodiment-aware egocentric binocular visual experiences in indoor environments. It models environmental and observer variation through generative scene synthesis, probabilistic object instantiation, appearance randomization, stochastic trajectory generation, and configurable binocular camera setups, producing synchronized videos with dense multimodal supervision such as depth maps, optical flow, surface normals, semantic maps, object coordinates, and camera poses. Using BinoGen, the authors created a dataset of over 20 million annotated images, demonstrating that incorporating this data improves real-world visual perception tasks like depth estimation, object detection, and video object tracking, and that embodiment-specific adaptation enhances performance while joint training enables a single model to perform competitively across different observer embodiments.

Object Concepts Emerge from Motion

The paper introduces a biologically inspired framework that learns object‑centric visual representations from raw videos without human annotations or camera calibration. By using motion boundaries detected via optical flow and clustering to create pseudo‑instance masks, the method supervises a single‑image encoder with pixel‑level pairwise metric learning. Training on 195 million pseudo‑labeled frames and expanding to 421 million frames through Motion‑Verified Self‑Training, the approach yields Swin‑based encoders that outperform or match supervised and self‑supervised baselines on tasks such as monocular depth estimation, 3D object detection, 3D occupancy prediction, and end‑to‑end planning.
