  • New Predicted Spiral Search Block Matching Algorithm - PSSBMA 

    Pika, J. (Společnost pro radioelektronické inženýrství, 2002-04)
    This article describes the modification of the full search algorithm ESBMA (Exhaustive Search Block Matching Algorithm), which leads up to 40% speed increase. The modification is based on the ESBMA motion field analysis ...

  • Performance of Basic Vector Directional Filters According to Used Angle Distance 

    Lukac, R. (Společnost pro radioelektronické inženýrství, 2002-04)
    Color images are typical examples of vector-valued signals. For that reason, vector processing represents an optimal approach. Although widely used vector filter is a vector median based on a reduced ordering, the directional ...

  • Application of Shape-Independent Orthogonal Transforms for Image Interpolation 

    Polec, J.; Pavlovicova, J.; Karlubikova, T. (Společnost pro radioelektronické inženýrství, 2002-04)
    In the contribution we develop a new method for object-oriented interpolation of images. It is an important tool in image processing, since using interpolation we can considerably decrease amount of data, necessary for ...

  • Analysis of Coplanar On-Chip Interconnects on Lossy Semiconducting Substrates 

    Ymeri, H.; Nauwelaers, B.; Maex, K.; Vandenberghe, S.; de Roest, D.; Stucchi, M. (Společnost pro radioelektronické inženýrství, 2002-04)
    In this paper, a method for analysis and modeling of coplanar transmission interconnect lines that are placed on top of silicon-silicon oxide substrates is presented. The potential function is expressed by series expansions ...

  • Improvements of Analog Neural Networks Based on Kalman Filter 

    Tobes, Z.; Raida, Zbyněk (Společnost pro radioelektronické inženýrství, 2002-04)
    In the paper, original improvements of recurrent analog neural networks, which are based on Kalman filter, are presented. These improvements eliminate some disadvantages of the classical Kalman neural network and enable a ...

  • The LFSR and BCA VHDL Models for Built-in Self-test Circuits 

    Mitrych, J. (Společnost pro radioelektronické inženýrství, 2002-04)
    The various test structures are proposed for BIST techniques [1], [2]. A typical structure used for generation of pseudo-random test sets is the linear feedback shift register (LFSR). The BIST techniques have wide application ...

  • Digital Realization of the Test Signal Generator Sin^2 20T 

    Ricny, V. (Společnost pro radioelektronické inženýrství, 2002-04)
    The paper deals with the digital implementation of the generator of test signal sin^2 20T. This function has a limited spectrum in the luminance and chrominance areas of the color composite signal. The signal is frequently ...

  • VHDL Models with Usage of the LFSR_PCKG Package 

    Kovalsky, J.; Vlcek, K.; Mitrych, J. (Společnost pro radioelektronické inženýrství, 2002-04)
    LFSRs (Linear Feedback Shift Registers) are very often used in the BIST (Built-In Self-Test) methodology. Implementation of the LFSRs to the design or application of digital system, which supports BIST techniques or which ...
