The package contains R-functions implementing the Propagation-Separation Approach to adaptive smoothing as described
in J. Polzehl and V. Spokoiny (2006) Propagation-Separation Approach for Local Likelihood Estimation,
Prob. Theory and Rel. Fields 135(3):335-362. and
J. Polzehl and V. Spokoiny (2004) Spatially adaptive regression estimation: Propagation-separation approach,
WIAS-Preprint 998. Additionally it contains an implementation of selected LPA-ICI pointwise adaptive
smoothing algorithms from the book V. Katkovnik, K. Egiazarian and J. Astola (2006). Local Approximation
Techniques in Signal and Image Processing, SPIE Press Monograph Vol. PM 157.
