PointConv: Deep Convolutional Networks on 3D Point Clouds

CVPR 2019 Wenxuan WuZhongang QiLi Fuxin

Unlike images which are represented in regular dense grids, 3D point clouds are irregular and unordered, hence applying convolution on them can be difficult. In this paper, we extend the dynamic filter to a new convolution operation, named PointConv... (read more)
