2D image classification and alignment in single-particle Cryo-EM
… and rotation alignment, we first propose a non-uniform discrete Fourier transform (NUDFT) to calculate the Fourier transform of an image in polar coordinates. Based on the proposed NUDFT, we develop a rotation-invariant feature extraction algorithm. After using principal component analysis …
