      Osharovskaya, E.V.; Ошаровська, О.В.; Ошаровская, Е.В.; Patlayenko, N.A.; Патлаєнко, М.О.; Патлаенко, Н.А.; Pyliavskyi, V.V.; Пілявський, В.В.; Пилявский, В.В. (Львівський національний університет ім. Івана Франка, 2018)
      This paper presents the results of measuring the signal-to-noise ratio at the boundary of object contours in highdefinition images after compression of the original digital stream based on the Fourier transform and the ...
    • FRACTAL CODING OF VIDEO SEQUENCES BY GENETIC ALGORITHM 

      Osharovskaya, E.V.; Patlaenko, N.A.; Ошаровська, О.В.; Патлаєнко, М.О.; Ошаровская, Е.В.; Патлаенко, Н.А. (ОНАЗ ім. О.С. Попова, 2017)
      The results of application of the modified genetic algorithm of fractal coding to still images and video sequences are presented. The dependence of the compression coefficient on the size of the rank block is obtained. ...
    • QUALITY INDICATORS FOR REPRODUCING FINE DETAILS OF DIGITAL IMAGES WITH TRESHOLD LIMITING OF SPECTRAL COMPONENTS 

      Osharovska, O.V.; Ошаровська, О.В.; Ошаровская, О.В.; Patlayenko, М.О.; Патлаєнко, М.О.; Патлаєнко, Н.О.; Samus, N.S.; Самусь, Н.С.; Самусь, Н.С. (Одеський національний університет імені І.І. Мечникова, 2018)
      The article considers the effect of compression of the information stream on high-definition image quality image parameters on the receiving side. In order to assess objectively the quality of the reconstructed images, two ...
