Temporal and volumetric denoising via quantile sparse image prior
Franziska Schirrmacher, Thomas Köhler, Tobias Lindenberger +7
This paper introduces an universal and structure-preserving regularization term, called quantile sparse image (QuaSI) prior. The prior is suitable for denoising images from various…
QuaSI: Quantile Sparse Image Prior for Spatio-Temporal Denoising of Retinal OCT Data
Franziska Schirrmacher, Thomas Köhler, Lennart Husvogt +3
Optical coherence tomography (OCT) enables high-resolution and non-invasive 3D imaging of the human retina but is inherently impaired by speckle noise. This paper introduces a spat…
Mixed one-bit compressive sensing with applications to overexposure correction for CT reconstruction
Xiaolin Huang, Yan Xia, Lei Shi +4
When a measurement falls outside the quantization or measurable range, it becomes saturated and cannot be used in classical reconstruction methods. For example, in C-arm angiograph…
A Self-Taught Artificial Agent for Multi-Physics Computational Model Personalization
Dominik Neumann, Tommaso Mansi, Lucian Itu +10
Personalization is the process of fitting a model to patient data, a critical step towards application of multi-physics computational models in clinical practice. Designing robust…
Super-Resolved Retinal Image Mosaicing
Thomas Köhler, Axel Heinrich, Andreas Maier +2
The acquisition of high-resolution retinal fundus images with a large field of view (FOV) is challenging due to technological, physiological and economic reasons. This paper propos…
3-D/2-D Registration of Cardiac Structures by 3-D Contrast Agent Distribution Estimation
Matthias Hoffmann, Christopher Kowalewski, Andreas Maier +3
For augmented fluoroscopy during cardiac catheter ablation procedures, a preoperatively acquired 3-D model of the left atrium of the patient can be registered to X-ray images. Ther…
