Time：2020/11/21 10:00-12:00
Tencent Meeting ID: 458 657 083
Abstract:
Sampling (i.e., up-sampling and down-sampling) is a commonly-used technique in 3D point cloud processing for improving reconstruction quality and saving acquisition cost/storage space/transmission bandwidth/computational complexity. In this talk, I will show our recent works on learning-based sampling frameworks for 3D point cloud data. Specifically, I will introduce a geometry-centric network for 3D point cloud up-sampling, which incorporates discrete differential geometry into deep learning elegantly, followed by a novel network for task-oriented 3D point cloud down-sampling, which is designed Bet365 app download the perspective of matrix optimization. Extensive experiments are provided to demonstrate the advantages of our framework over the existing approaches.
