  2. Comparison gallery of image scaling algorithms - Wikipedia

    For magnifying computer graphics with low resolution and few colors (usually from 2 to 256 colors), better results will be achieved by pixel art scaling algorithms such as hqx or xbr. These produce sharp edges and maintain high level of detail. Unfortunately due to the standardized size of 218x80 pixels, the "Wiki" image cannot use HQ4x or ...

    Step 1 – Find out who removed the image, and ask them why. At the top of the page there is a "history" tab. If you click on it, you see a list of all the edits made to the page. Try to determine which edit caused the removal of the image, and then go to that editor's talk page and ask them politely why it was removed.

    Mipmap. In computer graphics, mipmaps (also MIP maps) or pyramids[1][2][3] are pre-calculated, optimized sequences of images, each of which is a progressively lower resolution representation of the previous. The height and width of each image, or level, in the mipmap is a factor of two smaller than the previous level.

    en.wikipedia.org/wiki/Mini-map

    Mini-map. A mini-map or minimap is a miniature map HUD element that is often placed at a screen corner in video games to help players in orienting themselves within the game world. They are often only a small portion of the screen and must be selective in what details they display. Elements included on mini-maps vary by video game genre, but ...

    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.

  7. FITS - Wikipedia

    en.wikipedia.org/wiki/FITS

    Flexible Image Transport System (FITS) is an open standard defining a digital file format useful for storage, transmission and processing of data: formatted as multi-dimensional arrays (for example a 2D image), or tables. [3] FITS is the most commonly used digital file format in astronomy. The FITS standard was designed specifically for ...

    For guidance on the syntax for doing this, see Help:Infobox picture. In very brief summary, one hurdle that trips up many people when attempting to add an image to an infobox template is that most internally provide the wiki code that "wraps" the image. Accordingly, you do not usually add the brackets, number of pixels, and other code details ...

  9. Foveated imaging - Wikipedia

    en.wikipedia.org/wiki/Foveated_imaging

    Foveated imaging is a digital image processing technique in which the image resolution, or amount of detail, varies across the image according to one or more "fixation points". A fixation point indicates the highest resolution region of the image and corresponds to the center of the eye 's retina, the fovea. The location of a fixation point may ...
