PC$^2$-PU: Patch Correlation and Point Correlation for Effective Point Cloud Upsampling

1 code implementation • 20 Sep 2021 • Chen Long, Wenxiao Zhang, Ruihui Li, Hao Wang, Zhen Dong, Bisheng Yang

Point cloud upsampling is to densify a sparse point set acquired from 3D sensors, providing a denser representation for the underlying surface.

Detail Preserved Point Cloud Completion via Separated Feature Aggregation

1 code implementation • ECCV 2020 • Wenxiao Zhang, Qingan Yan, Chunxia Xiao

In this work, instead of using a global feature to recover the whole complete surface, we explore the functionality of multi-level features and aggregate different features to represent the known part and the missing part separately.
