In this paper, we propose a data ownership authentication method based on GNN backdoor watermarking, termed Graph Data Ownership Authentication(GDOA). Specifically, the data owner injects covert ...

To address this issue, we propose a phase unwrapping method based on vibrational phase shifting for 3D measurement. The method improves the conventional phase shifting fringes by changing the light ...

To address these challenges, there is a growing demand for methods that enable the efficient generation of high-precision 3D point cloud maps in urban areas by utilizing simpler and more ...
