Abstract-A study aimed at optimizing noisy image processing under conditions of strong additive noise has been performed. An algorithm of optimal signal processing was developed and a possibility of improving image quality due to the subtraction of excess additive noise (which limits the photodetector dynamic range) was substantiated. The possibility of technical implementation of noise subtraction due to forced recombination of charge carriers in the photodetector is experimentally confirmed. The proposed approach to design processing systems makes it possible to improve the quality of recorded images under noisy conditions without any changes in the photodetector design.

Сохранение структурной информации в системе твердое-жидкое-твердое обусловлено микронеоднородным строением металлических расплавов, унаследованным от исходных шихтовых материалов. Известно, что структурная информация может устойчиво сохраняться при фазовых переходах металлических систем из одного конденсированного состояния в другое [1, 2]. В связи с этим вопросам изучения взаимосвязи структуры и свойств в системе твердое-жидкое-твердое уделяется большое внимание. Наряду с вязкостью и поверхностным натяжением плотность металлических расплавов (ρ L) является одной из наиболее структурно-чувствительных УДК 621.74

The article considers the system of computer analysis of ECG and the software implementation of this system. The system provides for automatic recognition of singular points of ECG and automatic detection of ECG characteristic areas. In the design and implementation of the system there were widely used the finite automata. This allowed to visualize the logic of the system, to avoid design errors and to accelerate the process of creating the system.The analysis of test results developed by the team of the prototype of the computerized ECG analysis system with the advanced capabilities of automated search for characteristic sites allows us to conclude that the reliability of ECG interpretation by a specialist increases with a substantial reduction in the time required to perform this procedure. This positive effect is achieved through the implementation of the procedure for automatic recognition of special ECG points and the use of automated means of searching for ECG lines. The system increases the reliability of decoding ECG by a doctor-cardiologist for the purpose of diagnosis and significantly reduces the time to perform this procedure.
