This code implements a deep neural network for 3D point cloud semantic segmentation. It comes as a baseline for the benchmarkhttp://www.semantic3d.net/(reproduces DeepNet entry in reduced-8 track). It is written in C++/lua and is supposed to simplify starting to work with the benchmark....
3D street scene semantic segmentation is essential for urban understanding. However, supervised point cloud semantic segmentation networks heavily rely on expensive manual annotations and demonstrate limited generalization capabilities across datasets, which poses limitations in a range of downstream tasks. In...

In this case, an initial classification and/or semantic segmentation processing step is required. We use a classified ALS point cloud whose points are labelled according to their object class (building, ground, and unclassified). To group points belonging to one building, points are clustered by ...
Point cloud analysisSemantic segmentationScene comprehensionIn this paper, we propose a Geo-SceneEncoder framework to handle point cloud scene semantic segmentation, including a SceneEncoder to learn a scene prior, an advanced geometric kernel to learn geometry information from the point cloud, and a ...
Many point cloud segmentation methods rely on transferring irregular points into a voxel-based regular representation. Although voxel-based convolutions are useful for feature aggregation, they produce ambiguous or wrong predictions if a voxel contains points from different classes. Other approaches (such...
This letter presents a long-range contextual dependency enhanced network (LCDE-Net) for semantic segmentation of large-scale point cloud, which employs a U-shaped framework. Firstly, point clouds are subsampled with grid sampling and fed into convolutional layers to learn more representative local ...
