Spherical Fractal Convolutional Neural Networks for Point Cloud Recognition

CVPR 2019 Yongming Rao Jiwen Lu Jie Zhou

We present a generic, flexible and 3D rotation invariant framework based on spherical symmetry for point cloud recognition. By introducing regular icosahedral lattice and its fractals to approximate and discretize sphere, convolution can be easily implemented to process 3D points... (read more)
