The authors provide the main statements of the method of approximation of discontinuous functions of two variables that describe an image of the surface of a 2D body or an image of the internal structure of a 3D body in a certain plane, using the pro

The authors consider classes of functions that can be exactly reconstructed using the D’Alembert formula generalized by O. M. Lytvyn in 1989. This formula as a special case is known to yield the Taylor polynomial of the expansion of functions in on

The authors discuss the issue of estimating the error and optimizing the choice of parameters in Hermitian-type operators of interlineation of functions on a system of M parallel lines. To this end, the formulas of generalized Hermitian-type interlin

The paper develops a method for approximation of the discontinuous functions of two variables by discontinuous interlination splines using arbitrary triangular elements. Experimental data are one-sided traces of a function given along a system of lin

The method of constructing a mathematical model of the internal structure of the geological environment is considered for the case, where the function that describes this model has a discontinuity of the first kind. The model is proposed for use in m

The great role of Fourier coefficients in the digital processing of multidimensional signals is known. The classic cubic formulas for the calculation of Fourier coefficients use the values of an approximate function at individual points. Due to the a
