RACG-Ground: Ring-Adaptive Confidence Gating for LiDAR Ground Segmentation

LiDAR has been widely used in autonomous driving and robotic navigation, while ground segmentation is a key preprocessing step. However, existing methods often suffer from over segmentation, under segmentation or insufficient real-time performance. In this letter, RACG-Ground, Ring-Adaptive Confidence Gating is develop...

Frequency-aware elastic prototype boundary learning for long-tailed scene graph generation

A frequency-aware elastic prototype boundary learning framework, termed SGE-Net, that combines visual and semantic features with dynamic gating to provide more reliable relation features for the above boundary learning and introduces elastic boundary-aware distance calibration during inference.
