Discussion

Daryo Sep 20, 2019:
the human vision is really strange when you look at a blurred picture (with the right amount and right type of "blur") you see better what's in it than when looking at the same uncorrected picture - very sharp but full of distracting "noise".

One of the methods for "blurring" the picture is to replace each pixel by another value that is the average (plain or weighted) of that pixel and a number of surrounding pixels - THAT is called "moyenner" - and has preciously little to do with "defringing" which deals with high contrast edges (nor with "masking").

English term (edited): [hold "shift" to select mutiple values] to average
Selected

.... dont vous voulez utiliser la moyenne

Select a point in the preview window to specify the color to defringe;
hold "shift" to select mutiple values to average

Select a point in the preview window to specify the color to mask;
hold "shift" to select mutiple values to average

the point of the operation is to select a colour to "defringe" (or to "mask")

instead of selecting only one colour (of only one pixel) you can also select several pixels and use as "colour to defringe" (or to "mask") the colour that is the average of the colours of these selected pixels.


this is just the plainest calculation of an "average" of a set of values, nothing to do with "averaging" [=" moyenner"] as a mean of eliminating noise from a picture by deliberately blurring if - that option being called "average" BUT in the "blur" (the picture) submenu (=Enlever le bruit par moyennes locales).

pour moyenner

You select pixel and you compute the arithmetic mean of the value.

"Afin d’enlever plus de bruit, on peut moyenner plus de valeurs autour de chaque pixel. "
Peer comment(s):

agree Tony M : Yes, this horrible word has become widely accepted in applications like this, where we are talking about averaging things like signals or pixel values, rather than specifically a pure mathematical / statistical function.

disagree Daryo : the term does exist, but it applies to something else: to a method for creating blur by averaging each pixel with a number of surrounding pixels - not much to do with "defringing"

dont on souhaite établir la moyenne

"[...] afin de sélectionner plusieurs valeurs dont on souhaite établir la moyenne". Il est également possible de traduire par "[...] afin de sélectionner plusieurs valeurs dont une moyenne va être établie" pour éviter l'usage du pronom "on".

La traduction "à moyenner" est également possible (attention à l'emploi de "à", et non pas "pour"). Il s'agit d'un anglicisme courant et maintenant accepté (http://gdt.oqlf.gouv.qc.ca/ficheOqlf.aspx?Id_Fiche=17059624)... Le sens initial de "moyenner" était pourtant bien différent (https://www.larousse.fr/dictionnaires/francais/moyenner/5304...
Peer comment(s):

disagree Daryo : La traduction "à moyenner" est également possible - non, c'est autre chose dans les traitements d'images

Le verbe "moyenner" est utilisé dans le sens d'"établir une moyenne". L'encyclopédie Universalis l'emploie dans ce sens dans différents articles (aérodynamique, mission Herschel, neurosciences cognitives): https://www.universalis.fr/dictionnaire/moyenner/
