The beam-induced motion-correction method informally known as Bayesian Polishing will be discussed in detail. The method has been made available to the public in 2019 as part of Relion-3 and has been widely adopted since. The talk will focus on the Bayesian formulation of the problem and on the use of Gaussian processes to model our prior assumptions on the movement of particles embedded in the ice. A more recent adaptation of the method to estimate 3D motion in tomographic samples will also be briefly presented.
