* [https://www.tu-chemnitz.de/etit/proaut/publications/schubert19_IV.pdf Circular Convolutional Neural Networks (IV 2019)] proposes padding the left and right sides of each input and feature map using pixels such that the input wraps around. | * [https://www.tu-chemnitz.de/etit/proaut/publications/schubert19_IV.pdf Circular Convolutional Neural Networks (IV 2019)] proposes padding the left and right sides of each input and feature map using pixels such that the input wraps around. This works since equirectangular images wrap around on the x-axis. | ||
* [https://arxiv.org/abs/1811.08196 SpherePHD (CVPR 2019)] proposes using faces of an icosahedron as pixels. They propose a kernel which considers the neighboring 9 triangles of each triangle. | * [https://arxiv.org/abs/1811.08196 SpherePHD (CVPR 2019)] proposes using faces of an icosahedron as pixels.
