In this work, we propose OpenGraph, a novel open-vocabulary hierarchical graph representation designed for large-scale outdoor environments. OpenGraph initially extracts instances and their captions ...

An advanced artificial intelligence (AI) technology has been developed that can extract three-dimensional (3D) spatial structure and object information within indoor environments using just a single ...

In the field of design, the construction of a knowledge graph for 3D product models is crucial for obtaining design norms and successful cases. Traditional knowledge extraction methods rely on ...

DCGCN decomposes the 3D point cloud data of a molecule into three components: atomic sequence, atomic connectivity, and a distance map. From its connectivity and distance information, DCGCN captures ...
