CPCM: Contextual Point Cloud Modeling for Weakly-supervised Point Cloud Semantic Segmentation
ICCV 2023poster
We study the task of weakly-supervised point cloud semantic segmentation with sparse annotations (e.g., less than 0.1% points are labeled), aiming to reduce the expensive cost of dense annotations. Unfortunately, with extremely sparse annotated points, it is very difficult to extract both contextual…
