Abstract

Image processing combined with transmission electron microscopy is a powerful tool for investigation of size distribution of nano-objects. The high-resolution, bright- and dark-field images recorded on photo plates were digitalized and used as an input data for image analysis.
The Fourier filtering, autocorrelation, methods were applied for outline determination of Co precipitates.
The influence of digitising condition, size and shape of Fourier masks, and parameters of reference regions will be discussed in respect to obtained results.
