Beyond the Label Itself: Latent Labels Enhance Semi-supervised Point Cloud Panoptic Segmentation

no code implementations13 Dec 2023 Yujun Chen, Xin Tan, Zhizhong Zhang, Yanyun Qu, Yuan Xie

Second, in the Image Branch, we propose the Instance Position-scale Learning (IPSL) Module to learn and fuse the information of instance position and scale, which is from a 2D pre-trained detector and a type of latent label obtained from 3D to 2D projection.
