  • A universal hidden Markov tree image model 

    Romberg, Justin Keith (1999)
    Wavelet-domain hidden Markov models have proven to be useful tools for statistical signal and image processing. The hidden Markov tree (HMT) model captures the key features of the joint density of the wavelet coefficients ...
  • Code design and multiuser detection for code division multiple access systems with continuous phase modulation 

    Papasakellariou, Aristides (1996)
    The proliferation of wireless communications services combined with the limited spectrum availability have placed the bandwidth utilization as a major performance measure. Consequently, the bandwidth allocation technique ...
  • Multiscale geometric image processing 

    Romberg, Justin K. (2004)
    Since their introduction a little more than 10 years ago, wavelets have revolutionized image processing. Wavelet based algorithms define the state-of-the-art for applications including image coding (JPEG-2000), restoration, ...
  • Robot reliability through fuzzy Markov models 

    Leuschen, Martin Leslie (1997)
    In the past few years, new applications of robots have increased the importance of robotic reliability and fault tolerance. Standard approaches of reliability engineering rely on the probability model, which is often ...
