Label-supervised surgical instrument segmentation using temporal equivariance and semantic continuity

Qiyuan Wang, Yanzhe Liu, Shang Zhao, Rong Liu, S. Kevin Zhou

IROS 2025

In robotic surgery, instrument presence labels are typically recorded alongside video streams, offering a cost-effective alternative to manual annotations for segmentation tasks. Label-supervised surgical instrument segmentation (SIS), a weakly supervised segmentation setting where only instrument p

SPU-PMD: Self-Supervised Point Cloud Upsampling via Progressive Mesh Deformation

Yanzhe Liu, Rong Chen, Yushi Li, Yixi Li, Xuehou Tan

CVPR 2024poster

Despite the success of recent upsampling approaches generating high-resolution point sets with uniform distribution and meticulous structures is still challenging. Unlike existing methods that only take spatial information of the raw data into account we regard point cloud upsampling as generating d…
