A problem of automated image processing of transmission electron microscopy and its application value is considered in this paper. An automated algorithm for estimating the interplanar distances of the crystal structure of a substance from transmission electron microscopy images is proposed. The software implementation of the algorithm was developed and tested on several raster images, and the evaluation results were compared with the results obtained using the specialized software named Gatan Microscopy Suite v.1.8. The high degree of coincidence of the results showed the viability of the proposed approach and the prospects of its further development in the area of transmission electron microscopy images processing.
Specialized software that supports existing approaches to processing images of the crystal structure of materials for analyzing transmission electron microscopy images have a lot of different digital image processing methods, but major part of it are weakly automated. Automatic algorithm is able to make the crystal structure analysis more fast and effective process. The paper considers the problem of automated processing of SAED images of transmission electron microscopy. Proposed automated image processing algorithm based on methods of adaptive binarization and Watershed segmentation allows one to determine the distances on the diffraction pattern of a material sample on the image of transmission electron microscopy. The proposed algorithm has been tested on several SAED images, distances were calculated in automatic mode and compared with the results of semi-automatic measurement in Digital Micrograph GMS 1.8 software. The analysis of the results showed high agreement in considered cases, which let us assume that proposed algorithm has good development prospects.
