  • Yang, Xuguang (1998)
    Next, we consider the design of signal-adapted subband filter banks to be incorporated into our wavelet video coder, for the purpose of further improving compression efficiency, and for protection against channel errors ...

  • Servetto, Sergio Daniel (1999)
    Our presentation is divided into three main chapters: (1) One chapter is dedicated to the problem of defining stochastic models for image subband data. We present a Markov Random Field (MRF) model for this data as well as ...

  • Mihcak, Mehmet Kivanc (2002)
    Finally, we present a new approach to the watermarking problem that is based on traditional cryptographic arguments. Here, the attacker is assumed to have enough information about the algorithmic steps of information hiding ...
