  • Fractal Image Coding with Digital Watermarks 

    Candik, M.; Levicky, D.; Klenovicova, Z. (Společnost pro radioelektronické inženýrství, 2000-12)
    In this paper are presented some results of implementation of digital watermarking methods into image coding based on fractal principles. The paper focuses on two possible approaches of embedding digital watermarks into ...
  • Some Modifications of Fractal Image Coding 

    Levicky, D.; Candik, M.; Pundzak, R. (Společnost pro radioelektronické inženýrství, 1999-09)
    In this paper some modifications of fractal image coding are presented. Proposed methods are based on correlation coefficients computing as an alternative approach to searching of similarity between blocks. The convergence ...
  • Trigonometric Approximation in Fractal Image Coding 

    Candik, M. (Společnost pro radioelektronické inženýrství, 2001-04)
    In this paper is presented a new approach in fractal image coding based on trigonometric approximation. The least square approximation method is used for approximation of blocks in standard fractal image compression ...
