Open vocabulary recognition and classification are crucial for a comprehensive understanding of real-world 3D scenes.

In this article, a 3D geometry-based millimeter-wave channel model is proposed for reconfigurable intelligent surface (RIS)-assisted high-speed train communications. Remarkably, the RIS is attached to ...

Point clouds are generated by light imaging, detection and ranging (LIDAR) scanners or depth imaging cameras, which capture the geometry from the scanned objects with high accuracy. Unfortunately, ...
