Webour novel point set abstraction design with semantics. For point-based 3D detection, we (a) attach a binary segmen-tation module to the SA layer to identify valuable points from foreground and; (b) propose a novel sampling algo-rithm S-FPS to make abstracted point sets focus on object areas. Our design is lightweight and can be easily adopted WebDec 31, 2024 · We present a novel and high-performance 3D object detection framework, named PointVoxel-RCNN (PV-RCNN), for accurate 3D object detection from point clouds. Our proposed method deeply integrates both 3D voxel Convolutional Neural Network (CNN) and PointNet-based set abstraction to learn more discriminative point cloud features.

We remove the first PointNet Set Abstraction module and feed in the point features from 3D detector’s backbone to the second PointNet Set Abstraction module.
WebApr 8, 2024 · Sketch semantic segmentation presents great challenges, since sketches have simpler appearances and more levels of abstraction than natural images. To overcome these challenges, we propose a sketch semantic segmentation method. Concretely, we treat a sketch as a 2D point set and exploit the structures of strokes and the spatial position …
