CNNs on Surfaces using Rotation-Equivariant Features

SIGGRAPH 2020 Ruben WiersmaElmar EisemannKlaus Hildebrandt

This paper is concerned with a fundamental problem in geometric deep learning that arises in the construction of convolutional neural networks on surfaces. Due to curvature, the transport of filter kernels on surfaces results in a rotational ambiguity, which prevents a uniform alignment of these kernels on the surface... (read more)
