S2ANet: Combining local spectral and spatial point grouping for point cloud processing

Background: Despite the recent progress in 3D point cloud processing using deep convolutional neural networks, the inability to extract local features remains a challenging problem. In addition, existing methods consider only the spatial domain in the feature extraction process. Methods: In this pap...
