Median filter
The median filter is a non-linear digital filtering technique， often used to remove noise from an image or signal. Such noise reduction is a typical pre-processing step to improve the results of later processing (for example， edge detection on an image). Median filtering

median filter
21/10/2008 · A median filter works by setting， in turn， the value of each pixel in an image (except for the pixels on the border) to the median of the values of the pixels in a window surrounding the pixel. Median filters can be used to remove scattered noise from images and smooth them， while preserving the edges of objects in the image.

Weighted median
In statistics， a weighted median of a sample is the 50% weighted percentile. It was first proposed by F. Y. Edgeworth in 1888. Like the median， it is useful as an estimator of central tendency， robust against outliers. It allows for non-uniform statistical weights

Le filtre médian est un filtre numérique non linéaire， souvent utilisé pour la réduction de bruit. La réduction de bruit est une étape de prétraitement classique visant à améliorer les résultats de traitements futurs (détection de bords par exemple). La technique de filtre médian est largement utilisée en …

‘median’ tag wiki
Median can give you a better sense of where the typical middle case is than the average. The median is also very useful in signal and image processing， in the context of a moving median filter. This filter is usually used to reduce “salt and pepper” type noise， as well as spikes， because each output pixel or element contains the median value of the m-by-n neighborhood around that corresponding

Filter (Elektrotechnik) – Wikipedia

Als Filter (in der Fachsprache zumeist das/ein Filter[1]) werden in der Elektrotechnik und Nachrichtentechnik Schaltungen bezeichnet， die ein elektrisches Signal abhängig von der Frequenz in der Amplitude und in der Phasenlage verändern. Dadurch können unerwünschte Signalanteile abgeschwächt oder unterdrückt werden. Antennenweiche
