Joint Denoising of Cryo-EM Projection Images using Polar Transformers
Joakim Andén, Justus Sagemüller
Many imaging modalities involve reconstruction of unknown objects from collections of noisy projections related by random rotations. In one of these modalities, cryogenic electron…

Sparse wavefield reconstruction and denoising with boostlets
Elias Zea, Marco Laudato, Joakim Andén
Boostlets are spatiotemporal functions that decompose nondispersive wavefields into a collection of localized waveforms parametrized by dilations, hyperbolic rotations, and transla…
