MUSt3R: Multi-view Network for Stereo 3D Reconstruction

CVPR 2025highlight

DUSt3R introduced a novel paradigm in geometric computer vision by proposing a model that can provide dense and unconstrained Stereo 3D Reconstruction of arbitrary image collections with no prior information about camera calibration nor viewpoint poses. Under the hood, however, DUSt3R processes imag…

PanSt3R: Multi-view Consistent Panoptic Segmentation

ICCV 2025poster

Panoptic segmentation in 3D is a fundamental problem in scene understanding. Existing approaches typically rely on costly test-time optimizations (often based on NeRF) to consolidate 2D predictions of off-the-shelf panoptic segmentation methods into 3D. Instead, in this work, we propose a unified an…

Reasoning in Visual Navigation of End-to-end Trained Agents: A Dynamical Systems Approach

CVPR 2025highlight

Progress in Embodied AI has made it possible for end-to-end-trained agents to navigate in photo-realistic environments with high-level reasoning and zero-shot or language-conditioned behavior, but evaluations and benchmarks are still dominated by simulation. In this work, we focus on the fine-graine…

End-to-End (Instance)-Image Goal Navigation through Correspondence as an Emergent Phenomenon

ICLR 2024poster

Most recent work in goal oriented visual navigation resorts to large-scale machine learning in simulated environments. The main challenge lies in learning compact representations generalizable to unseen environments and in learning high-capacity perception modules capable of reasoning on high-dimens…

Learning to Navigate Efficiently and Precisely in Real Environments

CVPR 2024poster

In the context of autonomous navigation of terrestrial robots the creation of realistic models for agent dynamics and sensing is a widespread habit in the robotics literature and in commercial applications where they are used for model based control and/or for localization and mapping. The more rece…

Learning with a Mole: Transferable latent spatial representations for navigation without reconstruction

ICLR 2024poster

Agents navigating in 3D environments require some form of memory, which should hold a compact and actionable representation of the history of observations useful for decision taking and planning. In most end-to-end learning approaches the representation is latent and usually does not have a clearly…

CroCo v2: Improved Cross-view Completion Pre-training for Stereo Matching and Optical Flow

ICCV 2023poster

Despite impressive performance for high-level downstream tasks, self-supervised pre-training methods have not yet fully delivered on dense geometric vision tasks such as stereo matching or optical flow. The application of self-supervised concepts, such as instance discrimination or masked image mode…

CroCo: Self-Supervised Pre-training for 3D Vision Tasks by Cross-View Completion

NeurIPS 2022accept

Masked Image Modeling (MIM) has recently been established as a potent pre-training paradigm. A pretext task is constructed by masking patches in an input image, and this masked content is then predicted by a neural network using visible patches as sole input. This pre-training leads to state-of-the-…
