  • Discrete Orthogonal Transforms and Neural Networks for Image Interpolation 

    Oravec, M.; Polec, J. (Společnost pro radioelektronické inženýrství, 1999-09)
    In this contribution we present transform and neural network approaches to the interpolation of images. From transform point of view, the principles from [1] are modified for 1st and 2nd order interpolation. We present ...
  • Extrapolation of Incomplete Image Data with Discrete Orthogonal Transforms 

    Karlubikova, T.; Polec, J. (Společnost pro radioelektronické inženýrství, 2004-12)
    In image processing and transmission, interpolation and extrapolation are of great importance whenever missing pixels have to be filled in, and many methods have been proposed to solve this problem. In this paper we present ...
