A scalar per patch from pre-trained ViTs enables fast moving navigation in the real world

Steeven Janny, Leonid Antsfeld, Christian Wolf

Trained policies for real-world robotics rely on computer vision components, typically in the form of pre-trained visual encoders. These encoders are an essential component and it…

S-MUSt3R: Sliding Multi-view 3D Reconstruction

Leonid Antsfeld, Boris Chidlovskii, Yohann Cabon +2

The recent paradigm shift in 3D vision led to the rise of foundation models with remarkable capabilities in 3D perception from uncalibrated images. However, extending these models…

3D-Consistent Image Inpainting with Diffusion Models

Leonid Antsfeld, Boris Chidlovskii

We address the problem of 3D inconsistency of image inpainting based on diffusion models. We propose a generative model using image pairs that belong to the same scene. To achieve…

Self-supervised Pretraining and Finetuning for Monocular Depth and Visual Odometry

Boris Chidlovskii, Leonid Antsfeld

For the task of simultaneous monocular depth and visual odometry estimation, we propose learning self-supervised transformer-based models in two steps. Our first step consists in a…
