Orthogonal Dictionary Guided Shape Completion Network for Point Cloud

AAAI 2024technical

Point cloud shape completion, which aims to reconstruct the missing regions of the incomplete point clouds with plausible shapes, is an ill-posed and challenging task that benefits many downstream 3D applications. Prior approaches achieve this goal by employing a two-stage completion framework, gene…

Parametric Surface Constrained Upsampler Network for Point Cloud

AAAI 2023technical

Designing a point cloud upsampler, which aims to generate a clean and dense point cloud given a sparse point representation, is a fundamental and challenging problem in computer vision. A line of attempts achieves this goal by establishing a point-to-point mapping function via deep neural networks.…
