    A method to control bit rate while compressing predicted frames
    (IEEE, 2015) Barannik, V.; Musienko, A.; Othman Shadi, O. Y.; Kharchenko, N.
    A method to control bit rate while compressing video data subject to approaching maximal quality of the image has been proposed. We use the bisection method to find optimal parameters of the compressor. This method allows us to control the accuracy of the optimal values to find without doing the exhaustive search. Such an approach reduces the frame processing time for a video group.

    Development strategy bit rate control processing personnel predicts to increase the availability and integrity of information resources
    (IEEE, 2015) Kharchenko, N.; Hrinivetskaya, A.
    Strategy for bit rate control end equipment, which provides the best image quality for a given channel and the best time to process a single frame is considered. To implement the compression mechanism predicted frame is analyzed: format chroma subsampling, the decision threshold depending on the type of processing block in frame quality factor and quantization. The combination of selected options provides the flexibility to adapt to the required bandwidth while maintaining the required quality of the transmitted image.

    Selection of the Best Biometric Systems Taking into Account the Characteristics
    (IEEE, 2021) Bezruk, V.; Skoryk, Y.; Koltun, Yu.; Kharchenko, N.; Kobtseva, V.
    An analysis of very well-known biometric systems is made. The choice of the best biometric system according to the set of characteristics known by some methods of multicriteria optimization and the method of analysis of hierarchies is carried out. The findings show that the best type of biometric system is a technology based on the analysis of the iris.

    The issue of timely delivery of video traffic with controlled loss of quality
    (IEEE, 2016) Barannik, V. V.; Kharchenko, N.; Tverdokhleb, V. V.; Kulitsa, O.
    Need of development of new methods of coding and management of the bit speed of a video traffic for coordination with the capacity of a telecommunication network justifies.
