    A method for determining the parameters of an optical system during the spatial scanning of a biological solution
    (2018) Rybalka, A. V.; Megel, Y. E.; Kalimanova, I. I.; Shlyakhov, V. V.; Kovalenko, S. I.; Kovalenko, S. N.
    In research, control of biological processes for determining the motility of microorganisms, (estimation of the impact of chemical compounds, electrophoretic mobility, evaluation of severity of pathology, etc.) using a scanning optoelectronic system as the most effective means of solving applied problems, it is necessary to determine the objects number in the optical system field of vision since the measurement accuracy of the solution concentration and the objects motion speed in the solution depend on their number. In the article a probabilistic method for estimation the number of objects and the number of frames during frame-by-frame filming for providing a given accuracy with a given probability is presented.

    Automation of measurement of objects geometrical parameters
    (Технический университет - София - Технологии, 2017) Rybalka, A.; Megel, Y.; Kalimanova, I.; Kovalenko, S.; Kovalenko, S.
    The issues of automation of measurement of the basic physical and geometrical parameters of biological object and possibility to obtain quantitative characteristics by optical methods are considered in the article. The prospects of the method of pattern recognition to distinguish the contour of the object in order to increase descriptiveness and precision measurement are shown.
