Digital Darkfield Analysis of Lattice Fringe Images with ImageJ
نویسندگان
چکیده
Digital-darkfield analysis involves the spatial mapping of selected frequencies across a digitized image, much as analog (e.g. electron-optical) darkfield-imaging allows one to locate crystals responsible for a given diffraction spot. This analysis involves a type of image decomposition which, like wavelets, is intermediate between direct and reciprocal (spatial-frequency) space [1]. Digital-darkfield analysis is of particular use on images that have well defined spatial-frequencies in them, like lattice-fringe images of atomic-planes encountered edge-on by high-energy electrons in crystalline materials [2-10].

Spacing measurements of lattice fringes in HRTEM images using digital darkfield decomposition
In this thesis I present the progress I made in understanding, improving and applying a digital method for lattice fringe spacing measurements in HRTEM images. The method uses filtering in Fourier space to form complex valued dark field images. These images are bright where the image contains the selected periodicity and dark otherwise. The amplitude and phase information in these dark field im...
متن کاملGeometric Phase Analysis of High Resolution Electron Microscope Images
A new method is described for analysing high resolution lattice fringe images. The image is considered to be composed of a reduced set of major image periodicities. Each periodicity has an associated Fourier component which is allowed to vary as a function of position. It is shown that the local amplitude and geometric phase of lattice fringes can be determined in this way by filtering in Fouri...

The orientation dependence of thin-crystal lattice fringes can be gracefully quantified using fringe-visibility maps, a direct-space analog of Kikuchi maps Nishikawa and Kikuchi, Nature London 121, 1019 1928 . As in navigation of reciprocal space with the aid of Kikuchi lines, fringe-visibility maps facilitate acquisition of crystallographic information from lattice images. In particular, these...

The digital slide, or Whole Slide Image, is a digital image, acquired with specific scanners, that represents a complete tissue sample or cytological specimen at microscopic level. While Whole Slide image analysis is recognized among the most interesting opportunities, the typical size of such images-up to Gpixels- can be very demanding in terms of memory requirements. Thus, while algorithms an...
