Multi-label learning with contrastive cluster self-supervision for 3D hierarchical semantic segmentation

ICML 2026poster

3D hierarchical semantic segmentation (3DHS) is crucial for embodied intelligence that demands the coarse-to-fine grained and multi-hierarchy understanding of 3D scenes. 3DHS tasks can be addressed by multi-label learning, but facing two issues: I) learning multiple labels for each point with a shar…

Controllable 3D Outdoor Scene Generation via Scene Graphs

ICCV 2025poster

Three-dimensional scene generation is crucial in computer vision, with applications spanning autonomous driving and gaming. However, current methods offer limited or non-intuitive user control. In this work, we propose a method that uses scene graph as a user-friendly control format to generate outd…

Enhancing Sampling Protocol for Point Cloud Classification Against Corruptions

IJCAI 2025

Established sampling protocols for 3D point cloud learning, such as Farthest Point Sampling (FPS) and Fixed Sample Size (FSS), have long been relied upon. However, real-world data often suffer from corruptions, such as sensor noise, which violates the benign data assumption in current protocols. As

Pyramid Diffusion for Fine 3D Large Scene Generation

ECCV 2024oral

"Diffusion models have shown remarkable results in generating 2D images and small-scale 3D objects. However, their application to the synthesis of large-scale 3D scenes has been rarely explored. This is mainly due to the inherent complexity and bulky size of 3D scenery data, particularly outdoor sce…
