Fast Point Voxel Convolution Neural Network with Selective Feature Fusion for Point Cloud Semantic Segmentation
Xu Wang, Yuyan Li, Ye Duan
We present a novel lightweight convolutional neural network for point cloud analysis. In contrast to many current CNNs which increase receptive field by downsampling point cloud, o…

SPNet: Multi-Shell Kernel Convolution for Point Cloud Semantic Segmentation
Yuyan Li, Chuanmao Fan, Xu Wang +1
Feature encoding is essential for point cloud analysis. In this paper, we propose a novel point convolution operator named Shell Point Convolution (SPConv) for shape encoding and l…
