Large Scale Statistical Structure Recovery in Cryogenic Electron Microscopy
Abstract
Cryogenic electron microscopy intends to reconstruct biological particles on the nanometer scale from transmission images taken by a transmission electron microscope. In contrast to the image reconstruction problems in other fields of tomographic imaging, the reconstruction problem has the particular characteristics of having a huge number of 2D projection images of a bio-particle, with structural variations, while the projection geometry of the projections is unknown and random. This setting makes the statistical inversion problem particularly challenging where the state-of-the-art reconstruction methods require CPU months for processing a single particle. In this talk, we will discuss the reconstruction problem and the state-of-the-art, present our contributions, and sketch an outline for the future.
