aws - Adaptive Weights Smoothing
We provide a collection of R-functions implementing
adaptive smoothing procedures in 1D, 2D and 3D. This includes
the Propagation-Separation Approach to adaptive smoothing, the
Intersecting Confidence Intervals (ICI), variational approaches
and a non-local means filter. The package is described in
detail in Polzehl J, Papafitsoros K, Tabelow K (2020).
Patch-Wise Adaptive Weights Smoothing in R. Journal of
Statistical Software, 95(6), 1-27. <doi:10.18637/jss.v095.i06>,
Usage of the package in MR imaging is illustrated in Polzehl
and Tabelow (2023), Magnetic Resonance Brain Imaging, 2nd Ed.
