Latent Riemannian Flow Matching for Geometry-Grounded 3D Foundation Models

Lisa Weijler, Irene Ballester, Guofeng Mei +2

Geometric foundation models, such as the Visual Geometry Grounded Transformer (VGGT), provide strong 3D priors from unposed images. However, such models operate purely in a feed-fo…

TreeON: Reconstructing 3D Tree Point Clouds from Orthophotos and Heightmaps

Angeliki Grammatikaki, Johannes Eschner, Pedro Hermosilla +2

We present TreeON, a novel neural-based framework for reconstructing detailed 3D tree point clouds from sparse top-down geodata, using only a single orthophoto and its correspondin…

Exploring Modality Guidance to Enhance VFM-based Feature Fusion for UDA in 3D Semantic Segmentation

Johannes Spoecklberger, Wei Lin, Pedro Hermosilla +3

Vision Foundation Models (VFMs) have become a de facto choice for many downstream vision tasks, like image classification, image segmentation, and object localization. However, the…

Masked Scene Modeling: Narrowing the Gap Between Supervised and Self-Supervised Learning in 3D Scene Understanding

Pedro Hermosilla, Christian Stippel, Leon Sick

Self-supervised learning has transformed 2D computer vision by enabling models trained on large, unannotated datasets to provide versatile off-the-shelf features that perform simil…
