PIIE-DSA-Net for 3D Semantic Segmentation of Urban Indoor and Outdoor Datasets
In this paper, a 3D semantic segmentation method is proposed, in which a novel feature extraction framework is introduced assembling point initial information embedding (PIIE) and dynamic self-attention (DSA)—named PIIE-DSA-net. Ideal segmentation accuracy is a challenging task, since the sparse, ir...
