Neural Modulation Fields for Conditional Cone Beam Neural Tomography

no code implementations17 Jul 2023 Samuele Papa, David M. Knigge, Riccardo Valperga, Nikita Moriakov, Miltos Kofinas, Jan-Jakob Sonke, Efstratios Gavves

Conventional Computed Tomography (CT) methods require large numbers of noise-free projections for accurate density reconstructions, limiting their applicability to the more complex class of Cone Beam Geometry CT (CBCT) reconstruction.

Modelling Long Range Dependencies in $N$D: From Task-Specific to a General Purpose CNN

1 code implementation25 Jan 2023 David M. Knigge, David W. Romero, Albert Gu, Efstratios Gavves, Erik J. Bekkers, Jakub M. Tomczak, Mark Hoogendoorn, Jan-Jakob Sonke

Performant Convolutional Neural Network (CNN) architectures must be tailored to specific tasks in order to consider the length, resolution, and dimensionality of the input data.

Towards a General Purpose CNN for Long Range Dependencies in $N$D

1 code implementation7 Jun 2022 David W. Romero, David M. Knigge, Albert Gu, Erik J. Bekkers, Efstratios Gavves, Jakub M. Tomczak, Mark Hoogendoorn

The use of Convolutional Neural Networks (CNNs) is widespread in Deep Learning due to a range of desirable model properties which result in an efficient and effective machine learning framework.

Exploiting Redundancy: Separable Group Convolutional Networks on Lie Groups

1 code implementation25 Oct 2021 David M. Knigge, David W. Romero, Erik J. Bekkers

In addition, thanks to the increase in computational efficiency, we are able to implement G-CNNs equivariant to the $\mathrm{Sim(2)}$ group; the group of dilations, rotations and translations.
