    • A novel hierarchical coding scheme based on polar mass distribution 

      Öktem, Levent; Onural, Levent (IEEE, 1994)
      A novel method for coding arbitrarily shaped binary objects is presented. The main idea is expressing the binary object in terms of radial closed curves, that is, closed curves for which radius versus angle is a function. ...
    • Simulation of DigiCipher, an HDTV system proposal 

      Öktem, Levent (Bilkent University, 1991)
      In this thesis, the digital video encoder-decoder parts of an American HDTV system proposal, DigiCipher^^'^ is simulated in an image sequencer, based on the system description sheets. Numerical and subjective performances are ...
