[Retracted] PointLAE: A Point Cloud Semantic Segmentation Neural Network via Multifeature Aggregation for Large-Scale Application

Figure 3

Structure of PointLAE, which has 3 main parts, receives the point cloud multifeature information aggregated by ATSE, and the point cloud oversegmentation based on energy entropy, as well as the proposal of a type of point cloud feeling area according to the oversegmentation results. After going through Pointnet and the fully connected layer, the point cloud is segmented into multiple classes.
