The article presents the literature review about the application of stereology and image analysis for quantitative evaluation of the building materials structure. At the outset, the development of stereological methods and computer image analysis techniques in the study of building materials was provided. Then quantitative structure parameters were defined and their methods of determining were showed. In the paper, the application of image analysis for the determination of properties of the cement composites was reported, including: an assessment of the porosity of the hardened concrete, determination of the aggregate distribution in the cementitious matrix, the crack analysis. It was found that the leading problem of image analysis is the process of sample preparation in order to obtain the correct extraction of examinated phase, and measurement automation process.

Abstract Globalization and complexity of the PCB supply chain has made hardware assurance a challenging task. An automated system to extract the Bill of Materials (BoM) can save time and resources during the authentication process, however, there are numerous imaging modalities and image analysis techniques that can be used to create such a system. In this paper we review different imaging modalities and their pros and cons for automatic PCB inspection. In addition, image analysis techniques commonly used for such images are reviewed in a systematic way to provide a direction for future research in this area.

This paper describes the research aimed at developing an effective quality assessment method for potato tubers using neural image analysis techniques. Nowadays, the methods used to identify damage and diseases are time-consuming, require specialized knowledge, and often rely on subjective judgment. This study showed the use of the developed neural model as a tool supporting the evaluation of potato tubers during the sorting process in the storage room.
