The purpose of this work is to develop an algorithm for recognizing shrinkage defects on metal alloys. The steps for image processing are described. When analyzing the algorithm, a description is presented for each step, followed by a software implementation. The final step, after using the methods of the algorithm, is to count the contours of the defects. To demonstrate the functionality of the software, random photos of the metal body in the section were taken, where defects in the form of gas pores can be directly observed. The software, with the correct selection of input data, processes the image with high accuracy, minimizing errors in calculating defects. Using the proposed algorithms reduces the diagnostic time.

Symmetry detection is an important task that arises in MRI analysis, TEM microscopy and other scientific and industrial problems. Current methods of symmetry detection usually analyse SIFT invariants or use voting schemas. The article proposes and analyses an optimization problem that can be used to describe the image symmetry detection pipeline in terms of correlation and similarity. The article also describes an algorithm that solves the aforementioned optimization problem using a ransom sample consensus voting scheme, thus bringing the proposed method closer to other RANSAC-based methods. It is shown that an implementation based on the proposed model outperforms SIFT-based detectors, and stays in row with other voting-based methods; it is also shown that the algorithm's parameters could be adjusted for specific tasks to improve the detection quality. The article also compares the proposed method with other existing solutions in terms of accuracy and precision; visualizations are also included.

The existing architecture of the Unified Automated Information System of Customs Authorities (UAIS TO) does not fully comply with modern requirements and the goals and objectives of the FCS of Russia. The problems of desynchronization and multiple duplication of data in numerous automated information subsystems, software complexes, information and reference systems and various software tasks that make up the specialized software of the UAIS TO create prerequisites for the occurrence of emergency situations, which leads to the likelihood of stopping data transmission during customs operations , delays in the release of goods and problems with the functioning of other regulated procedures. Proposals for improving the UAIS TO are presented in terms of technical architecture, in terms of information and software infrastructure and in terms of functional architecture such as: modernization, taking into account the trends of import substitution, increasing the computing power of the data center, improving the telecommunications infrastructure (high channel capacity, uninterrupted, guaranteed data transmission); centralization of information and software tools; implementation of a functional subsystem of a unified analytical storage of information.

The presented article describes the modeling of a communication system (hereinafter SS) organized by a plurality of communication nodes of a public communication network (hereinafter SS SSN) and its elements. The task of modeling is to obtain interrelated initial data on the set of features for each investigated SS of the SSNS at each moment of the model time, taking into account the implemented activation processes and the logic of SS functioning. The process of functioning with the SS as a source of features is studied using a complex analytical and simulation model, since deterministic and random factors are taken into account for its development. The manifestation of signs is a complex process, since the SS is constantly in dynamics. However, the increasing intensity of the increase in the use of communication means and the load in communication channels leads to an increase in the number of manifested set of signs. The reasons for the manifestation of many signs are such factors as: dynamics of movement of the USS of the SSOP; modes of operation of SSOP elements, etc. All of these factors are used in the model as activating the manifestation of many features.
