报告内容介绍:
Weakly supervised point cloud segmentation aims to learn a segmentation model using only a few labelled points in 3D scenes, which greatly reduces the efforts for obtaining dense annotations on 3D point clouds. Existing methods remain challenging to accurately segment 3D point clouds since limited annotated data may lead to insufficient guidance on unlabeled data. In this talk, I will present our recent weakly supervised methods for semantic segmentation and instance segmentation based on consistency learning and label propagation. I will also talk about our recent method for weakly supervised learning on 3D point cloud sequences (4D point clouds). Self-supervised learning is another important learning scheme to learn from unlabelled data. I will introduce our self-supervised learning methods for scene flow estimation on 3D point clouds.
