GAPNet: Graph Attention based Point Neural Network for Exploiting Local Feature of Point Cloud Hengshuang Zhao Li Jiang Chi-Wing Fu Jiaya Jia The Chinese University of Hong Kong Tencent Youtu Lab 论文地址:https://arxiv.org/abs/1905.08705
Automatic building extraction and delineation from airborne LiDAR point cloud data of urban environments is still a challenging task due to the variety and complexity at which buildings appear. The Medial Axis Transform (MAT) is able to describe the geometric shape and topology of an object, but ...
Point cloud classification is the basic link of point cloud analysis and application. Some studies have used graph convolutional neural network to process point cloud classification (Te, Hu, Zheng, & Guo, 2018). What needs further research is to improve the query efficiency by changing the ...
