Image processing for crystal structure determination by high resolution electron microscopy imaging

A new approach to crystal structure determination based on a single high resolution electron microscope image and the corresponding electron diffraction pattern is introduced. This is, in fact, a kind of image processing by means of an electron diffraction analysis technique and contains two steps: image deconvolution and resolution enhancement. In the first step the image, taken under arbitrary de-focussed conditions, is transformed into the structure image; in the second step the image resolution is enhanced by a phase extension technique. The resolution of the final structure image exceeds the resolution limit of the electron microscopy
