  • Fast Tracking RLS Adaptation Algorithms of the Second-Order Volterra Digital Filters 

    Vasko, J.; Kocur, D. (Společnost pro radioelektronické inženýrství, 1995-04)
    Two new fast tracking exponentially weighted conventional recursive least-squares (RLS) algorithms of adaptation of the adaptive Volterra filters (AVF) for time-varying systems are presented. The new algorithms are based ...
  • The Methods of Design and Implementation of Stack Filters for Image Processing 

    Drutarovsky, M.; Marchevsky, S. (Společnost pro radioelektronické inženýrství, 1995-04)
    This paper deals with a large class of nonlinear digital filters, the stack filters, which contain all combinations and compositions of rank order operators within a finite window. Attention is given to design and effective ...
  • Gray Code ADC Based on an Analog Neural Circuit 

    Daponte, P.; Grimaldi, D.; Michaeli, L. (Společnost pro radioelektronické inženýrství, 1995-04)
    In this paper a new neural ADC design is presented, which is based on the idea to replace all functional components needed in the ADC block scheme by a simple connection of neurons. Transformation of ADC functional scheme ...
  • Spline Interpolation of Image 

    Mihalik, J.; Zavacky, J.; Kuba, I. (Společnost pro radioelektronické inženýrství, 1995-04)
    This paper presents the use of B spline functions in various digital signal processing applications. The theory of one-dimensional B spline interpolation is briefly reviewed, followed by its extending to two dimensions. ...
  • A Two Layer Hybrid Image Coder 

    Levicky, D.; Matus, E.; Kral, P. (Společnost pro radioelektronické inženýrství, 1995-04)
    This paper presents a new idea of a two layer hybrid image coder based on visual pattern image coding of original image and residual image by means of the wavelet transform. At first contours are extracted from the original ...
