SymmetryNet: Learning to Predict Reflectional and Rotational Symmetries of 3D Shapes from Single-View RGB-D Images [article]

Yifei Shi, Junwen Huang, Hongjia Zhang, Xin Xu, Szymon Rusinkiewicz, Kai Xu
2020 arXiv   pre-print
We propose an end-to-end deep neural network which is able to predict both reflectional and rotational symmetries of 3D objects present in the input RGB-D image.  ...  We study the problem of symmetry detection of 3D shapes from single-view RGB-D images, where severely missing data renders geometric detection approach infeasible.  ...  of College of Intelligence Science and Technology, NUDT (2020006, 2020008) and NSF grant IIS-1815070.  ...

Learning to Detect 3D Reflection Symmetry for Single-View Reconstruction [article]

Yichao Zhou, Shichen Liu, Yi Ma
2020 arXiv   pre-print
3D reconstruction from a single RGB image is a challenging problem in computer vision.  ...  In this work, we focus on object-level 3D reconstruction and present a geometry-based end-to-end deep learning framework that first detects the mirror plane of reflection symmetry that commonly exists  ...  However, unlike multi-view stereopsis, previous single-view methods hardly exploit the geometric constraints between the input RGB image and the resulting 3D shape.  ...

Learning to Detect 3D Symmetry From Single-View RGB-D Images With Weak Supervision

Yifei Shi, Xin Xu, Junhua Xi, Xiaochang Hu, Dewen Hu, Kai Xu
2022
In this work, we present a 3D symmetry detection approach to detect symmetry from single-view RGB-D images without using symmetry supervision.  ...  Moreover, to facilitate end-to-end network training and multiple symmetry detection, we introduce a new symmetry parametrization for the learning-based symmetry estimation of both reflectional and rotational  ...  This work was supported in part by NSFC (61825305, 62002379), National Key Research and Development Program of China (2018YFB1305105, 2018AAA0102200), and the Zhejiang Lab's International Talent Fund for  ...
