SPDC: A SUPER-POINT AND POINT COMBINING BASED DUAL-SCALE CONTRASTIVE LEARNING NETWORK FOR POINT CLOUD SEMANTIC SEGMENTATION
Semantic segmentation of point clouds is one of the fundamental tasks of point cloud processing and is the basis for other downstream tasks. Deep learning has become the main method to solve point cloud processing. Most existing 3D deep learning models require large amounts of point cloud data to dr...
