This paper describes an approach to solving the problem of fast pattern recognition with image co-ordinate detection and measurement under undefined noise and signal conditions. An analysis of the use of the W-transform method as a basis for image comparison algorithms was carried out. Image comparison algorithms with noise robustness were developed.
In this work, possible options for constructing optical systems for analysing the dynamic signals of objects characteristic of the conditions of material processing are proposed. A feature of such systems is the use for automated process equipment. Thus, the use of analysers based on acousto-optical processes, as well as on the basis of fiber Bragg elements, has been proposed. The paper presents the main analytical dependencies for determining the current state of the object. Also, graphical dependences of the experimental results of the study using an acousto-optic system are shown, which show possible changes in the state of objects as a result of their operation.

Modern 3D scanning technologies have revolutionized various industries, including healthcare and biomedical engineering. This research explores the application of 3D scanning in the field of medicine, focusing on the representation of 3D hand data using the SIREN (Sinusoidal Representation Network) approach. 3D scanning plays a vital role in hand prosthetics, enabling the development of personalized models that accurately replicate the shape and size of real hands. This allows for the production of prostheses tailored to the specific needs of patients, facilitating their reintegration into active life. RealSense 3D cameras, developed by Intel, are among the leading technologies for 3D scanning. However, the effective utilization of implicit representation of 3D data, such as SIREN, presents challenges in ensuring compatibility with the features and limitations of existing 3D scanning technologies. This study analyses the potential of SIREN for 3D hand data representation, addressing the existing constraints and limitations. By leveraging the capabilities of RealSense cameras and the flexibility of SIREN, we aim to enhance the analysis and processing of 3D data, opening new avenues for prosthesis design.
This section contains the results of studying the relationship between 3D distributions of the optical anisotropy parameters of self-assembled soft matter films - polycrystalline blood film networks and layer-by-layer phase maps of the module and phase of the parameters of the "two-point" (correlation) Stokes vector of a microscopic image. The values and ranges of changes in the statistical moments of the 1st to 4th orders, which characterize the layered maps of the module and phase of the Stokes vector parameters of microscopic images of blood films taken from patients with adenocarcinoma of the prostate, were determined. Physically substantiated and experimentally determined the effectiveness of 3D Stokes-correlation mapping of blood film preparations in differentiating malignant conditions of prostate tissue with varying severity.
In the evidence-based diagnosis of nasal breathing disorders and the planning of corrective surgical procedures, it is not sufficient to examine only the general characteristics of airflow - averaged values of aerodynamic parameters such as airflow rate, pressure drop, and aerodynamic nasal resistance. It is necessary to investigate the effect of airflow on the mucosa at the micro level, which, when pathological conditions develop, leads to excessive drying of the nasal cavity surface. To do this, it is necessary to compare the width of the laminar boundary layer – the parietal region, where the maximum change in airflow velocity is observed, and the height of the nasal mucosa irregularity. The calculated values of the laminar airflow boundary layer were obtained from model representations of the complex spatial configuration of the nasal cavity using a circular channel of equivalent diameter.
