Research Highlights

Dr. Weixiao Gao presented this work at CVPR 2025 in Nashville, showcasing our three key contributions:

  1. First large-scale benchmark: 2.5km² urban textured meshes with part-level semantic labels across 21 object classes
  2. Novel annotation framework: Unified tool for efficient labeling of mesh faces and textures
  3. Comprehensive analysis: Benchmarking of 3D semantic segmentation methods on urban objects
