Learning 3D Semantics from Pose-Noisy 2D Images with Hierarchical Full Attention Network

1 code implementation17 Apr 2022 Yuhang He, Lin Chen, Junkun Xie, Long Chen

This motivates us to conduct a "task transfer" paradigm so that 3D semantic segmentation benefits from aggregating 2D semantic cues, albeit pose noises are contained in 2D image observations.
