PointCNN: Convolution On $\mathcal{X}$-Transformed Points

NeurIPS 2018 Yangyan LiRui BuMingchao SunWei WuXinhan DiBaoquan Chen

We present a simple and general framework for feature learning from point clouds. The key to the success of CNNs is the convolution operator that is capable of leveraging spatially-local correlation in data represented densely in grids (e.g. images)... (read more)
