TLDR
The vector median filter (VMF) as discussed by the authors is an extension of the MF, which outputs for each window location a number of data elements, and is obtained as a VMF special case by adjusting the VMF parameters.About:

A switching median filter with boundary discriminative noise detection for extremely corrupted images
Pei-Eng Ng,Kai-Kuang Ma +1 more
TL;DR: Results clearly show that the proposed switching median filter substantially outperforms all existing median-based filters, in terms of suppressing impulse noise while preserving image details, and yet, the proposed BDND is algorithmically simple, suitable for real-time implementation and application.

A New Directional Weighted Median Filter for Removal of Random-Valued Impulse Noise
Yiqiu Dong,Shufang Xu +1 more
TL;DR: Extensive simulations show that the proposed filter not only can provide better performance of suppressing impulse with high noise level but can preserve more detail features, even thin lines.

Vector directional filters-a new class of multichannel image processing filters
TL;DR: It is shown that VDF can achieve very good filtering results for various noise source models, and provides a link between single-channel image processing and multichannel image processing where both the direction and the magnitude of the image vectors play an important role in the resulting image.

Color filter array demosaicking: new method and performance measures
Wenmiao Lu,Yap-Peng Tan +1 more
TL;DR: The proposed demosaicking method consists of an interpolation step that estimates missing color values by exploiting spatial and spectral correlations among neighboring pixels, and a post-processing step that suppresses noticeable demosaicks artifacts by adaptive median filtering.

A fast two-dimensional median filtering algorithm
Thomas S. Huang,G. Yang,G. Tang +2 more
TL;DR: A fast algorithm for two-dimensional median filtering based on storing and updating the gray level histogram of the picture elements in the window is presented, which is much faster than conventional sorting methods.

A theoretical analysis of the properties of median filters
Neal C. Gallagher,G. Wise +1 more
TL;DR: In this article, the authors derived necessary and sufficient conditions for a signal to be invariant under a specific form of median filtering and proved that the form of successive median filtering of a signal (i.e., the filtered output is itself again filtered) eventually reduces the original signal to an invariant signal called a root signal.

A generalization of median filtering using linear combinations of order statistics
TL;DR: In this paper, the authors consider a class of nonlinear filters whose output is given by a linear combination of the order statistics of the input sequence, and choose the coefficients in the linear combination to minimize the output MSE for several noise distributions.
