Spherical Convolutional Neural Network for 3D Point Clouds

21 May 2018Huan LeiNaveed AkhtarAjmal Mian

We propose a neural network for 3D point cloud processing that exploits `spherical' convolution kernels and octree partitioning of space. The proposed metric-based spherical kernels systematically quantize point neighborhoods to identify local geometric structures in data, while maintaining the properties of translation-invariance and asymmetry...
