SVD-DIP: Overcoming the Overfitting Problem in DIP-based CT Reconstruction

1 code implementation28 Mar 2023 Marco Nittscher, Michael Lameter, Riccardo Barbano, Johannes Leuschner, Bangti Jin, Peter Maass

The deep image prior (DIP) is a well-established unsupervised deep learning method for image reconstruction; yet it is far from being flawless.

Over the last years, deep learning methods have become an increasingly popular choice to solve tasks from the field of inverse problems.

Computed Tomography Reconstruction Using Deep Image Prior and Learned Reconstruction Methods

1 code implementation10 Mar 2020 Daniel Otero Baguer, Johannes Leuschner, Maximilian Schmidt

In this work, we investigate the application of deep learning methods for computed tomography in the context of having a low-data regime.

The LoDoPaB-CT Dataset: A Benchmark Dataset for Low-Dose CT Reconstruction Methods

1 code implementation1 Oct 2019 Johannes Leuschner, Maximilian Schmidt, Daniel Otero Baguer, Peter Maaß

Deep Learning approaches for solving Inverse Problems in imaging have become very effective and are demonstrated to be quite competitive in the field.
