2D image classification and alignment in single-particle Cryo-EM
… viewing directions but with different in-plane rotations; (2) rotation alignment of images in each class. To perform rotation-invariant classification and rotation alignment, we first propose a non-uniform discrete Fourier transform (NUDFT) to calculate the Fourier transform of an image in polar …
