I haven't been able to find the explanation of this technic on the English wikipedia.
There is an article about [http://en.wikipedia.org/wiki/Convolution convolution] but it does not talk at all about how to apply it on image processing. In the French area it is in this article:

==Border Handling==
I don't know if this is common knowledge that I'm missing, but maybe the task should specify how to handle the border pixels. I think the standard method is padding the image with zeroes (or something of that equivalence) so that the convolution can be taken on all pixels. Some functions, like edge-detection, are benefited from the zero-padding. Others, like smoothing or blurring, are benefited more by not padding and not taking the convolution on the border pixels, or by doing some kind of partial convolution using only valid pixels.
I would suggest making it clear which should be used in the task, and perhaps make other options extra credit.--[[User:Ooorah|Ooorah]] ([[User talk:Ooorah|talk]]) 13:54, 30 June 2014 (UTC)
