TearingNet: Point Cloud Autoencoder to Learn Topology-Friendly Representations [article]

Jiahao Pang, Duanshun Li, Dong Tian
2021 arXiv   pre-print
Experimentation shows the superiority of our proposal in terms of reconstructing point clouds as well as generating more topology-friendly representations than benchmarks.  ...  By breaking the edges of a primitive graph, it tears the graph into patches or with holes to emulate the topology of a target point cloud, leading to faithful reconstructions.  ...  Hence, the Folding network and the Tearing network interact with each other for high-quality reconstructions.  ...

Pop-Out Motion: 3D-Aware Image Deformation via Learning the Shape Laplacian [article]

Jihyun Lee, Minhyuk Sung, Hyunjin Kim, Tae-Kyun Kim
2022 arXiv   pre-print
While our framework leverages 2D-to-3D reconstruction, we argue that reconstruction is not sufficient for realistic deformations due to the vulnerability to topological errors.  ...  In this paper, we present a 3D-aware image deformation method with minimal restrictions on shape category and deformation type.  ...  However, most of these existing methods are vulnerable to topological errors when ambiguous structures (e.g., spatially adjacent surfaces, high-curvature surface) exist.  ...

2010 2010 Shape Modeling International Conference  
In such cases, automatic surface reconstruction schemes tend to produce incorrect surface topology.  ...  We show that the curve skeletons we extract provide an intuitive and easy-to-manipulate structure for effective topology modification, leading to more faithful surface reconstruction.  ...  However, reconstruction algorithms often produce high-resolution surface models -editing an improperly reconstructed surface thus requires the user to interact with a large number of polygons.  ...
