  2. Image rectification - Wikipedia

    en.wikipedia.org/wiki/Image_rectification

    If the images to be rectified are taken from camera pairs without geometric distortion, this calculation can easily be made with a linear transformation.X & Y rotation puts the images on the same plane, scaling makes the image frames be the same size and Z rotation & skew adjustments make the image pixel rows directly line up [citation needed].

    A free image may be either public domain, or released under a free license, such as CC-BY-SA. Free images can be used in any article where their presence would add value. As long as there is a consensus among the editors working on an article that the image is appropriate for the article, it's safe to say that it can remain in an article. Free ...

  5. ReactiveX - Wikipedia

    en.wikipedia.org/wiki/ReactiveX

    ReactiveX (Rx, also known as Reactive Extensions) is a software library originally created by Microsoft that allows imperative programming languages to operate on sequences of data regardless of whether the data is synchronous or asynchronous. It provides a set of sequence operators that operate on each item in the sequence.

  6. Photopolymer - Wikipedia

    en.wikipedia.org/wiki/Photopolymer

    The image is cut in slices; each slice is then reconstructed through radiation curing of the liquid polymer, converting the image into a solid object. Photopolymers used in 3D imaging processes require sufficient cross-linking and should ideally be designed to have minimal volume shrinkage upon polymerization in order to avoid distortion of the ...

  7. Interactivity - Wikipedia

    en.wikipedia.org/wiki/Interactivity

    Not interactive, when a message is not related to previous messages. Reactive, when a message is related only to one immediately previous message. Interactive, when a message is related to a number of previous messages and to the relationship between them. [2] One body of research has made a strong distinction between interaction and interactivity.

  8. Reactive user interface - Wikipedia

    en.wikipedia.org/wiki/Reactive_user_interface

    A human-to-computer user interface is said to be "reactive" if it has the following characteristics: The user is immediately aware of the effect of each "gesture". Gestures can be keystrokes, mouse clicks, menu selections, or more esoteric inputs. The user is always aware of the state of their data. [1] Did I just save those changes?

  9. Reactive dye - Wikipedia

    en.wikipedia.org/wiki/Reactive_dye

    In a reactive dye, a chromophore (an atom or group whose presence is responsible for the colour of a compound) contains a substituent that reacts with the substrate. Reactive dyes have good fastness properties owing to the covalent bonding that occurs during dyeing. Reactive dyeing is the most important method for coloring cellulose fibers.
