Densely annotating LiDAR point clouds is costly, which often restrains the scalability of fully- supervised learning methods. In this work, we study the underexplored semi-supervised …
Recent advances in 3D semantic segmentation with deep neural networks have shown remarkable success, with rapid performance increase on available datasets. However …
The rapid advancement of deep learning models is often attributed to their ability to leverage massive training data. In contrast such privilege has not yet fully benefited 3D deep learning …
The intrinsic rotation invariance lies at the core of matching point clouds with handcrafted descriptors. However, it is widely despised by recent deep matchers that obtain the rotation …
Semantic segmentation of large-scale mobile laser scanning (MLS) point clouds is essential for urban scene understanding. However, most of the existing semantic segmentation …
Abstract We present NeRF-Det, a novel method for indoor 3D detection with posed RGB images as input. Unlike existing indoor 3D detection methods that struggle to model scene …
Modern 3D semantic instance segmentation approaches predominantly rely on specialized voting mechanisms followed by carefully designed geometric clustering techniques. Building …
