Multi-Dimensional Weighted Median: The Module "Wmedian" of the Mastrave Modelling Library. de Rigo , D. In Semantic Array Programming with Mastrave - Introduction to Semantic Computational Modelling. Mastrave project, 2012.
abstract   bibtex   
Weighted median (WM) filtering is a well known technique for dealing with noisy images and a variety of WM-based algorithms have been proposed as effective ways for reducing uncertainties or reconstructing degraded signals by means of available information with heterogeneous reliability. Here a generalized module for applying weighted median filtering to multi-dimensional arrays of information with associated multi-dimensional arrays of corresponding weights is presented. Weights may be associated to single elements or to groups of elements along given dimensions of the multi-dimensional arrays. The filtered information derives from a reduction operator applied along a custom dimension.
