Equivariant Light Field Convolution and Transformer

no code implementations30 Dec 2022 Yinshuang Xu, Jiahui Lei, Kostas Daniilidis

We model the ray space, the domain of the light field, as a homogeneous space of $SE(3)$ and introduce the $SE(3)$-equivariant convolution in ray space.

Unified Fourier-based Kernel and Nonlinearity Design for Equivariant Networks on Homogeneous Spaces

no code implementations16 Jun 2022 Yinshuang Xu, Jiahui Lei, Edgar Dobriban, Kostas Daniilidis

We present a unified derivation of kernels via the Fourier domain by leveraging the sparsity of Fourier coefficients of the lifted feature fields.

Equivariant Multi-View Networks

1 code implementation ICCV 2019 Carlos Esteves, Yinshuang Xu, Christine Allen-Blanchette, Kostas Daniilidis

Several popular approaches to 3D vision tasks process multiple views of the input independently with deep neural networks pre-trained on natural images, achieving view permutation invariance through a single round of pooling over all views.
