• Artificial Neural Network for Displacement Vectors Determination 

    Levicky, D.; Bohmann, P. (Společnost pro radioelektronické inženýrství, 1997-09)
    An artificial neural network (NN) for displacement vectors (DV) determination is presented in this paper. DV are computed in areas which are essential for image analysis and computer vision, in areas where are edges, lines, ...
  • Diurnal and Seasonal Variations of Water Vapour and Cloud Water Attenuation in Microwave Frequency Bands 

    Fiser, O.; Rezacova, D. (Společnost pro radioelektronické inženýrství, 1997-09)
    20 years of radiosonde data from the aerological station Prague-Libus were analysed to evaluate integrated values of water vapour content and cloud water content. Both parameters are proportional to the attenuation in ...
  • Unconventional Tocographic Signal Analysis 

    Vidiscakova, J.; Pucik, J. (Společnost pro radioelektronické inženýrství, 1997-09)
    Spectrum estimation belongs to the most frequent problems solved by the digital stochastic signal processing. The application of the unconventional method of spectrum estimation based on maximum entropy approach introduced ...

    The paper is devoted to the development of the analog electronic switch for video signals. The simple linear equivalent diagram of the integrated circuit CMOS 4066 on the basis of measurements its transfer characteristics ...
  • Comparison of Propagation over Irregular Terrain 

    Schejbal, V. (Společnost pro radioelektronické inženýrství, 1997-09)
    Various cases of electromagnetic wave propagation have been solved such as two obstacles with the sharp edges or the spherical earth especially for low altitude propagation considering several combinations of antenna and ...
  • Several Remarks on Fractal Image Block Coding 

    Dedera, L.; Chmurny, J. (Společnost pro radioelektronické inženýrství, 1997-09)
    In this paper the dependence of PSNR on the size of both a codebook pool and range blocks is compared. The statistical properties of the values of transformation coefficients and distances between coded range blocks and ...
