Ordering methods for multivariate RCRS filters
Different types of mappings for ordering of multivariate data are considered. The resulting orderings are then used to extend the rank conditioned rank selection (RCRS) filters such that they operate on multivariate data, such as color images. Experimental results and comparison of different ordering strategies are then presented.
متن کاملMultichannel L filters based on reduced ordering
Nonlinear multichannel signal processing is an emerging research topic with numerous applications. In this paper we use the so-called reduced ordering (R-ordering) principle to introduce a new family of L lters for vector-valued observations. The coeecients of the proposed lters can be deduced so that the lters are optimal with respect to the output mean squared error. Expressions for the uncon...
متن کاملDistance Measures for Reduced Ordering Based Vector Filters
Reduced ordering based vector filters have proved successful in removing long-tailed noise from color images while preserving edges and fine image details. These filters commonly utilize variants of the Minkowski distance to order the color vectors with the aim of distinguishing between noisy and noise-free vectors. In this paper, we review various alternative distance measures and evaluate the...
متن کاملMultichannel L filters based on marginal data ordering
Absfruct-The extension of single-channel nonlinear filters whose output is a linear combination of the order statistics of the input samples to the multichannel case is presented in this paper. The subordering principle of marginal ordering (41-ordering) is used for multivariate data ordering. Assuming a multichannel signal corrupted by additive white multivariate noise whose components are gen...
متن کاملSemi-G-filters, Stonean filters, MTL-filters, divisible filters, BL-filters and regular filters in residuated lattices
At present, the filter theory of $BL$textit{-}algebras has been widelystudied, and some important results have been published (see for examplecite{4}, cite{5}, cite{xi}, cite{6}, cite{7}). In other works such ascite{BP}, cite{vii}, cite{xiii}, cite{xvi} a study of a filter theory inthe more general setting of residuated lattices is done, generalizing thatfor $BL$textit{-}algebras. Note that fil...
