Shearlets as Feature Extractor for Semantic Edge Detection: The Model-Based and Data-Driven Realm
Héctor Andrade-Loarca, Gitta Kutyniok, Ozan Öktem
Semantic edge detection has recently gained a lot of attention as an image processing task, mainly due to its wide range of real-world applications. This is based on the fact that…
Spatiotemporal PET reconstruction using ML-EM with learned diffeomorphic deformation
Ozan Öktem, Camille Pouchol, Olivier Verdier
Patient movement in emission tomography deteriorates reconstruction quality because of motion blur. Gating the data improves the situation somewhat: each gate contains a movement p…
Multi-Scale Learned Iterative Reconstruction
Andreas Hauptmann, Jonas Adler, Simon Arridge +1
Model-based learned iterative reconstruction methods have recently been shown to outperform classical reconstruction algorithms. Applicability of these methods to large scale inver…
Extraction of digital wavefront sets using applied harmonic analysis and deep neural networks
Héctor Andrade-Loarca, Gitta Kutyniok, Ozan Öktem +1
Microlocal analysis provides deep insight into singularity structures and is often crucial for solving inverse problems, predominately, in imaging sciences. Of particular importanc…
