PointSIFT: A SIFT-like Network Module for 3D Point Cloud Semantic Segmentation

2 Jul 2018Mingyang JiangYiran WuTianqi ZhaoZelin ZhaoCewu Lu

Recently, 3D understanding research sheds light on extracting features from point cloud directly, which requires effective shape pattern description of point clouds. Inspired by the outstanding 2D shape descriptor SIFT, we design a module called PointSIFT that encodes information of different orientations and is adaptive to scale of shape... (read more)
