Robust Point Cloud Processing through Positional Embedding

1 code implementation1 Sep 2023 Jianqiao Zheng, Xueqian Li, Sameera Ramasinghe, Simon Lucey

End-to-end trained per-point embeddings are an essential ingredient of any state-of-the-art 3D point cloud processing such as detection or alignment.

Point Cloud Classification

Fast Neural Scene Flow

1 code implementation ICCV 2023 Xueqian Li, Jianqiao Zheng, Francesco Ferroni, Jhony Kaesemodel Pontes, Simon Lucey

Neural Scene Flow Prior (NSFP) is of significant interest to the vision community due to its inherent robustness to out-of-distribution (OOD) effects and its ability to deal with dense lidar points.

Autonomous Driving Self-supervised Scene Flow Estimation

Trading Positional Complexity vs. Deepness in Coordinate Networks

1 code implementation18 May 2022 Jianqiao Zheng, Sameera Ramasinghe, Xueqian Li, Simon Lucey

It is well noted that coordinate-based MLPs benefit -- in terms of preserving high-frequency information -- through the encoding of coordinate positions as an array of Fourier features.
