Development of the Anisotropic Filtration Method for Automated Recognition of Authenticity of Banknotes by their Images
(2019) Nevliudov, I. Sh.; Novoselov, S. P.; Sychova, O. V.
This article describes the device and control program for automated recognition of authenticity of banknotes. A technique for pre-processing the image of banknotes for improving the quality of recognition is presented. The analysis of the use of anisotropic filtration in recognition of the authenticity of banknotes has been carried out. The results of experimental studies are given.
The Autoconvolution Method Use for Positioning Photonic Crystal Fibers
(2019) Filipenko, O. I.; Sychova, O. V.; Chala, O. O.
In this paper, the autoconvolution method was investigated to determine the position of the longitudinal axis of the photonic crystal fiber and to determine the center of the mode field in the cross section. Knowing the center of the PCF mode field, one can determine the cross section in which the diameter of the mode field will be maximal. This allows a more precise positioning of two identical PCF during connection. The proposed method allows improving the quality of the positioning of the PCF by transverse, angular, longitudinal displacements, and also by the mutual angle of rotation of the connected PCFs.
