Interpolation-Aware Padding for 3D Sparse Convolutional Neural Networks

1 code implementation ICCV 2021 Yu-Qi Yang, Peng-Shuai Wang, Yang Liu

For fine-grained 3D vision tasks where point-wise features are essential, like semantic segmentation and 3D detection, our network achieves higher prediction accuracy than the existing networks using the nearest neighbor interpolation or the normalized trilinear interpolation with the zero-padding or the octree-padding scheme.

Spline Positional Encoding for Learning 3D Implicit Signed Distance Fields

1 code implementation3 Jun 2021 Peng-Shuai Wang, Yang Liu, Yu-Qi Yang, Xin Tong

Multilayer perceptrons (MLPs) have been successfully used to represent 3D shapes implicitly and compactly, by mapping 3D coordinates to the corresponding signed distance values or occupancy values.

Unsupervised 3D Learning for Shape Analysis via Multiresolution Instance Discrimination

1 code implementation3 Aug 2020 Peng-Shuai Wang, Yu-Qi Yang, Qian-Fang Zou, Zhirong Wu, Yang Liu, Xin Tong

Although unsupervised feature learning has demonstrated its advantages to reducing the workload of data labeling and network design in many fields, existing unsupervised 3D learning methods still cannot offer a generic network for various shape analysis tasks with competitive performance to supervised methods.

PFCNN: Convolutional Neural Networks on 3D Surfaces Using Parallel Frames

1 code implementation CVPR 2020 Yu-Qi Yang, Shilin Liu, Hao Pan, Yang Liu, Xin Tong

Surface meshes are widely used shape representations and capture finer geometry data than point clouds or volumetric grids, but are challenging to apply CNNs directly due to their non-Euclidean structure.
