Provides a data structure for a queue of integers whose get() method returns the median element. The interface is similar to the standard Queue module, with an added method top() to retrieve the median without removing it.
Implementation of Progressive Switching Median Filter
Decision based median filter for high density noise
Untrimmed decision based median filter for high density impulse noise
Maintains sorted data as new elements are added and old one removed as a sliding window advances over a stream of data. Also gives fast indexed access to value. Running time per median update is proportional to the log of the window size.
Statistical Calculator calculates minimum, maximum, mean, median, mode, percentage unique, range, midrange, standard deviation, quartiles and more.
Weighted Median Filter:
It is same as median filter, only difference is the mask is not empty. It will having some weight (or values) and averaged.
The steps to perform weighted median filtering are as follows:
1) Assume a 3x3...
The adaptive median filter is discussed in recent designline article about embedded MATLAB block

B = HMF(A,N) performs hybrid median filtering of the matrix A using a NxN box. Hybrid median filtering preserves edges better than a NxN square kernel-based median filter because data from different spatial directions are ranked separately. Three...
This routine calculates the median squared error of a linear function, and can be used with fminsearch as a robust linear regression (see help LinearMedianSquaredError).
It should be very easy to extend the example code to handle...
This function implements approximately median unbiased (MU) estimation of the AR(p) model following Andrews, D.W.K and H.-Y. Chen (1994), "Approximately Median-Unbiased Estimation of Autoregressive Models," Journal of Business &...
Nonlinear median smoothers were popularized by John Tukey some years ago. The M-files in this suite are the embodiment of several. Rows or columns of a data matrix are smoothed individually. A contents file gives details and sample code.
This toolbox contains a set of functions which can be used to compute the Least Median of Squares regression, the Reweighted Least Squares regression, the accociated location and scale estiamtors, and the Minimum Volume Ellipsoid. The concept is...
This program can be used to compute the median path loss based on Hata model
Pitch determination and voice quality analysis using subharmonic-to-harmonic ratio.
There are also some post-processing routines available, such as de-step filter, median filter, and linear filter. For more information, please see...
The MATLAB function in TSK.m analyzes a dose-response curve and calculates the median dose (for instance, the lethal dose for 50% of the population (LD50)) using the Trimmed Spearman-Karber method. This is an alternative to dose-response analysis...
MEDIAN_POLISH(X) fits an additive model to a 2D input matrix, X, assuming a decomposition of (constant + rows + columns).
Median polishing is useful for removing spatial trends in the data by alternately removing medians from the rows...

This function gets the key values for a descriptive statistics such as mean, std, mode, median, quartiles and percentiles. This includes the five- and seven-number summary.
Input x must be a vector or a matrix where each column of x is...
I just need to simply plot the 5 and 95 percentile as well as mean.
The cross mark implies median.
