Multi-target detection with application to cryo-electron microscopy
Tamir Bendory, Nicolas Boumal, William Leeb +2
We consider the multi-target detection problem of recovering a set of signals that appear multiple times at unknown locations in a noisy measurement. In the low noise regime, one c…

3D ab initio modeling in cryo-EM by autocorrelation analysis
Eitan Levin, Tamir Bendory, Nicolas Boumal +2
Single-Particle Reconstruction (SPR) in Cryo-Electron Microscopy (cryo-EM) is the task of estimating the 3D structure of a molecule from a set of noisy 2D projections, taken from u…
