Median filtering is a nonlinear operation often used in image processing to reduce "salt and pepper" noise. A median filter is more effective than convolution when the goal is to simultaneously reduce noise and preserve edges. For information about performance considerations, seeordfilt2. ...

Order of the one-dimensional median filter, specified as a positive integer scalar. Whennis odd,y(k)is the median ofx(k-(n-1)/2:k+(n-1)/2). Whennis even,y(k)is the median ofx(k-n/2:k+(n/2)-1). In this case, the function sorts the numbers and takes the average of the...
A median filter in images works the same way, only in 2D. So you take not only the values (pixels) that are left or right, but all the values that surround the sample (pixel) you are in. In MATLAB, check medfilt1 and medfilt2 ;) . ThemeCopy doc medfilt1; doc medfilt2; Anywa...
One of the most widespread techniques in demosaiced image postprocessing is median filtering. Such a filter has been used for years to remove impulse noise in grey-level images, but it also efficiently removes color artifacts without damaging local color variations. Freeman (1988) was the first ...

In addition, since each component is filtered independently, the filter outputs can combine to produce colors not present in the original image. The advantage of marginal processing is the computational simplicity. 2.4.2 Vector WM Filter (WVM) A more logical extension, yet more computationally ...
