BARONI, M. P. M. A.; TEIXEIRA, S. R; DIXON, J. B.  e  WHITE, G. N.. Application of image analysis software to interpretation of high resolution photomicrographs of clay minerals. Cerâmica [online]. 2006, vol.52, n.322, pp.179-184. ISSN 0366-6913.  http://dx.doi.org/10.1590/S0366-69132006000200010.

The main objective of this paper is to show the potential image analysis on microscopy images interpretation of clay minerals. An image analysis software was applied to manipulate High-Resolution Transmission Electron Microscopy images of clays to improve them. Afterwards some parameters such as interplanar spacing were measured. It is also possible to measure others parameters like the angle between crossed lattice fringes, grain morphology, orientation, elongation, and crystallite sizes. The technique involves the application of fast Fourier transforms to single particles, application of the spike-boost program accessory to improve the images, and after that it is applied the inverse FFT. Although the program can be used to other interesting applications (for example, metallographic analysis of optical photomicrographs) in this paper the results obtained from the analysis of some clays minerals lattice fringes are shown.

Palavras-chave : image analysis; clays; high resolution microscopy.
