  2. Document comparison - Wikipedia

    en.wikipedia.org/wiki/Document_comparison

    With the advent of personal computers and the ubiquity of word processing software, the need arose to find a way to manage changes made to document versions shared via disk, and later email. The importance of mitigating risks associated with potential document changes became essential as the amount of document and revision sharing increased.

  3. Word processor - Wikipedia

    en.wikipedia.org/wiki/Word_processor

    A word processor (WP) [1] [2] is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features.. Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers.

  4. Office Open XML file formats - Wikipedia

    en.wikipedia.org/wiki/Office_Open_XML_file_formats

    A basic package contains an XML file called [Content_Types].xml at the root, along with three directories: _rels, docProps, and a directory specific for the document type (for example, in a .docx word processing package, there would be a word directory). The word directory contains the document.xml file which is the core content of the document.

  5. Image subtraction - Wikipedia

    en.wikipedia.org/wiki/Image_subtraction

    The complexity of the pre-processing needed before differencing varies with the type of image, but is essential to ensure good subtraction of static features. This is commonly used in fields such as time-domain astronomy (known primarily as difference imaging ) to find objects that fluctuate in brightness or move.

    The KDE diff tool Kompare. Editing documents, program code, or any data always risks introducing errors. Displaying the differences between two or more sets of data, file comparison tools can make computing simpler, and more efficient by focusing on new data and ignoring what did not change.

    Composite image showing JPG and PNG image compression. Left side of the image is from a JPEG image, showing lossy artefacts; the right side is from a PNG image. In the late 1980s, digital images became more common, and standards for lossless image compression emerged. In the early 1990s, lossy compression methods began to be widely used. [14]

  9. Image scaling - Wikipedia

    en.wikipedia.org/wiki/Image_scaling

    Image scaling can be interpreted as a form of image resampling or image reconstruction from the view of the Nyquist sampling theorem.According to the theorem, downsampling to a smaller image from a higher-resolution original can only be carried out after applying a suitable 2D anti-aliasing filter to prevent aliasing artifacts.
