Performs Contextual Median Filter

Description

This function performs the Contextual Median Filter (CMF) algorithm proposed by Belkin & O'Reilly (2009), based on the pseudo-code written on the paper.

Usage

contextualMF(X)

Arguments

X	A numeric matrix object used for apply filters.

Details

Following the definition of CMF, since imagine v.2.0.0, times argument will not be available anymore.

imagine offers the CMF algorithm but for the using to find out oceanographic fronts, it is recommended to see and use the functions of the grec package.

Value

contextualMF returns a matrix object with the same dimensions of X.
