Unlike common shift-invariant regularizers, non-uniform refinement systematically removes noise from disordered regions, while retaining signal useful for aligning particle images, yielding dramatically improved resolution and 3D map quality in many cases, especially for membrane proteins (Nature methods 17.12 (2020): 1214-1221; https://www.nature.com/articles/s41592-020-00990-8).
