Reconstructing classes of 3D FRI signals from sampled tomographic projections at unknown angles

no code implementations15 Apr 2024 Renke Wang, Francien G. Bossema, Thierry Blu, Pier Luigi Dragotti

By using the divergence theorem, we are able to retrieve the projected vertices of the polyhedron from the sampled tomographic projections, and then we show how to retrieve the 3D object and the projection angles from this information.

Empowering Networks With Scale and Rotation Equivariance Using A Similarity Convolution

no code implementations1 Mar 2023 Zikai Sun, Thierry Blu

The translational equivariant nature of Convolutional Neural Networks (CNNs) is a reason for its great success in computer vision.

Denoising of Three-Dimensional Fast Spin Echo Magnetic Resonance Images of Knee Joints using Spatial-Variant Noise-Relevant Residual Learning of Convolution Neural Network

no code implementations21 Apr 2022 Shutian Zhao, Donal G. Cahill, Siyue Li, Fan Xiao, Thierry Blu, James F Griffith, Weitian Chen

In this study, inherent true noise information from 2-NEX acquisition was used to develop a deep-learning model based on residual learning of convolutional neural network (CNN), and this model was used to suppress the noise in 3D FSE MR images of knee joints.
