Joint Data and Feature Augmentation for Self-Supervised Representation Learning on Point Clouds

no code implementations2 Nov 2022 Zhuheng Lu, Yuewei Dai, Weiqing Li, Zhiyong Su

To address the issues, we propose a simple but efficient augmentation fusion contrastive learning framework to combine data augmentations in Euclidean space and feature augmentations in feature space.

AS-PD: An Arbitrary-Size Downsampling Framework for Point Clouds

no code implementations2 Nov 2022 Peng Zhang, Ruoyin Xie, Jinsheng Sun, Weiqing Li, Zhiyong Su

Given an input point cloud of arbitrary size, we first perform a task-agnostic pre-sampling on the input point cloud to a specified sample size.
