Particularly, high-precision and fast-acting methods for calculating averaged image profiles, multi-level signal interpolation, visual quality enhancement and oriented image filtering, image alignment of objects using genetic algorithms, multilevel analysis of power spectrums, detection of the spatial position of line segments, circles and ellipses on images are developed. The high-precision methods of filtration and deconvolution of signals, a fast-acting method of training of artificial neural networks were further developed. Using the complex image processing by a variety of interrelated methods enhances the speed and (or) accuracy of these methods by an order of magnitude. At the same time, the proposed approaches make it possible to track the dynamics of structural changes of the investigated objects and to determine their quantitative characteristics. Objective criteria for the diagnosis of various pathological conditions of human organs are also formulated. Product Description popup.authors Balovsyak Sergiy V. Venkel Tetiana V.
