Program Complex for Analysis and Treatment Echo-Pulse Images

Development of the method for decomposition of superpositions of unknown pulsed signals using the second­order adaptive spectral analysis

“…However, we can use methods [10,11] to reconstruct medical images only. Studies [12][13][14][15][16][17] propose methods of numerical analysis of signals of various forms [12], which make it possible to code the diversity of signals [13], to estimate parameters of unknown distributions [14], to detect a selected region based on a global contrast [15], to segment images based on algorithm of fuzzy C-averages [16], to estimate generative models [17]. However, the proposed methods allow solving a small class of highly specialized problems and they are difficult to apply in practice.…”

“…Despite high efficiency in processing of large-volume of multidimensional data, such methods do not solve the problems of signal processing and time series [34] effectively enough. In addition, existing software tools [12] for analysis of echo-pulse images are very slow.…”

“…A wide range of levels, such as vibration, noise, humidity, temperature, as well as a change in parameters of technological process over a wide range, is characteristic of the mining, shipbuilding, machine-building, casting, rolling and other machining industries. Such changes in technological parameters and influences exerted by the external working environment significantly affect the accuracy of measuring a controlled magnitude [11][12][13]. Each of the factors that causes the error, typically under laboratory conditions, can be measured and separately taken into consideration in the results of measurements.…”

“…Given the impact of the specified factors, the results of measurement by each sensor, along with a predictable systematic error of the measured magnitude, include an additional random error, predetermined by a change in the modes of its operation [4][5][6][7][8][9][10][11]. The sensors that are built on the Hall effect, as well as other semiconductor sensors, have a pronounced temperature dependence and the non-linearity of characteristics [12]. These are only two of the factors among all that determine the accuracy of measurement by a given type of sensors.…”
