Abstract

The analysis of particle images displaying the same orientation in the electron micrographs is carried out by enhancement of auto-correlations of image densities as a function of the spatial coordinates of single particle images. The averaging of the spatial correlations, which is "incoherent" since it does not require alignment of the individual images, is compared to existing coherent averaging methods of enhancement using lattices and single particle images aligned by cross correlations.
