Image restoration: Image restoration focuses on solving the problem = + where is the blurry image that should be restored, is the blur kernel, is the additive noise and is the original image we wish to recover. The traditional filter which is used to solve this problem is the Wiener Filter.
Don't try to save disk space on the images server by giving up useful information. Keep the source: If the image was generated from data (e.g. a graph in Microsoft Excel), the data and file (e.g. spreadsheet) should be included so new data can be added to the graph, and/or the source of the data should be cited.
Excel at using Excel with these keyboard hotkeys that will save you minutes of time—and hours of aggravation. The post 80 of the Most Useful Excel Shortcuts appeared first on Reader's Digest.
The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest-neighbor interpolation. Other scaling methods below are better at preserving smooth contours in the image.
This page in a nutshell: Blurry images should not be used on Wikipedia. Wikipedia’s primary mission is to produce a “free” or “ libre ” encyclopedia of the highest quality. To that end, and with Wikipedia’s continued emergence as a leader in the field of collaborative research, it is becoming necessary to encourage editors to ...
In fact, it is the same data image, and when viewed full-size, it is already downloaded to the computer (from the wiki-servers) as the full GIF image.

center – shifts the image to center between left/right margins; Each of the above sizing options can be used in any image link coded into a Wikipedia page, in the form [[File:Example.jpg|thumb|upright|left|Description]].
