UrbanBIS: a Large-scale Benchmark for Fine-grained Urban Building Instance Segmentation

Guoqing Yang, Hui Huang

SegmentationComputational EfficiencyConvolutional Neural NetworkGraph Neural NetworkScore-based ModelContrastive LearningPoint CloudBenchmark

🎯 What it does: This paper proposes UrbanBIS — a large-scale 3D point cloud dataset for urban areas, containing 250 million points, covering an area of 10.78 km², and including fine-grained building category and instance annotations. Based on this dataset, we developed an end-to-end building instance segmentation framework called B-Seg.

Variational quasi-harmonic maps for computing diffeomorphisms

Yu Wang, J. Solomon

Optimization

🎯 What it does: A variational quasi-harmonic mapping is proposed to compute smooth injective (invertible) mappings, and the problem is transformed into an optimal control problem in the parameter space of elliptic partial differential equations. By minimizing a function family, exact injective discrete triangular mesh mappings are obtained.

Virtual Mirrors: Non-Line-of-Sight Imaging Beyond the Third Bounce

Diego Royo (Universidad de Zaragoza), Julio Marco (Universidad de Zaragoza)

Neural Radiance FieldOptical FlowImagePoint CloudComputed TomographyReview/Survey PaperPhysics Related

🎯 What it does: Leveraging the principle of virtual mirrors in the fluctuation domain, this paper proposes using higher-order (fourth and fifth-order) reflected light to achieve non-line-of-sight (NLOS) imaging, addressing the limitations of traditional third-order rebound NLOS imaging, such as the missing cone (null-reconstruction space) and single-corner observation constraints;

Rohan Sawhney (Carnegie Mellon University), Keenan Crane (Carnegie Mellon University)

OptimizationComputational EfficiencyPoint CloudMeshTabularPhysics Related

🎯 What it does: Proposed a new mesh-free Monte Carlo method called Walk on Stars (WoSt), for solving linear elliptic PDEs (such as the Poisson equation) with mixed Neumann and Dirichlet boundary conditions, enabling direct solutions for arbitrarily complex geometries.
