WebWe propose channel de-differentiation to handle the ob- vious distribution imbalance between the maaped coorid- nates and the mapped last-stage features in each stage of set abstraction (SA) in a PointNet++ [3] model. An illus- tration is shown in Fig.1. This may lead to an ignorance of the input of coordinates in the last few layers of MLPs. Web20 Oct 2024 · (2) Small objects are easily blocked which breaks the shape of their meshes in 3D point cloud. In this paper, we propose a pillar set abstraction (PSA) and foreground point compensation (FPC) and design a point-based detection network, PSA-Det3D, to improve the detection performance for small object. good birthday gifts for an 11 year old girl https://fourde-mattress.com
