  • Discrete pulse transform of images and applications 
    Fabris-Rotelli, Inger Nicolette (University of Pretoria, 2013-05-17)
    The LULU operators Ln and Un operate on neighbourhoods of size n. The Discrete Pulse Transform (DPT) of images is obtained via recursive peeling of so-called local maximum and minimum sets with the LULU operators as n ...
  • LULU operators on multidimensional arrays and applications 
    Fabris-Rotelli, Inger Nicolette (University of Pretoria, 2010-08-17)
    The LULU operators, Ln and Un, are smoothers, that is they smooth data received as a signal. They are nonlinear and this nonlinearity makes them more robust but also more complicated to study since the projection theorem ...
