Convergence Properties of Score-Based Models using Graduated Optimisation for Linear Inverse Problems

no code implementations29 Apr 2024 Pascal Fernsel, Željko Kereta, Alexander Denker

In this work, we show that score-based generative models (SGMs) can be used in a graduated optimisation framework to solve inverse problems.

Image Reconstruction via Deep Image Prior Subspaces

1 code implementation20 Feb 2023 Riccardo Barbano, Javier Antorán, Johannes Leuschner, José Miguel Hernández-Lobato, Bangti Jin, Željko Kereta

Deep learning has been widely used for solving image reconstruction tasks but its deployability has been held back due to the shortage of high-quality training data.

Quantifying Sources of Uncertainty in Deep Learning-Based Image Reconstruction

no code implementations17 Nov 2020 Riccardo Barbano, Željko Kereta, Chen Zhang, Andreas Hauptmann, Simon Arridge, Bangti Jin

Image reconstruction methods based on deep neural networks have shown outstanding performance, equalling or exceeding the state-of-the-art results of conventional approaches, but often do not provide uncertainty information about the reconstruction.
