  2. Graphical time warping - Wikipedia

    en.wikipedia.org/wiki/Graphical_time_warping

    Graphical time warping (GTW) is a framework for jointly aligning multiple pairs of time series or sequences. [1] GTW considers both the alignment accuracy of each ...

  3. Image warping - Wikipedia

    en.wikipedia.org/wiki/Image_warping

    Image warping example. Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing [1]). The same techniques are equally applicable to video.

  4. Image geometry correction - Wikipedia

    en.wikipedia.org/wiki/Image_geometry_correction

    The simplest application of image geometry correction is a specific case known as keystone distortion correction derived from Keystone effect.Keystone distortion gets its name from the symmetric trapezoidal distortion resulting from misaligned projector placement in the vertical dimension (although the term is generally applied to the non-symmetric quadrilateral shape that occurs from an off ...

  5. Dynamic time warping - Wikipedia

    en.wikipedia.org/wiki/Dynamic_time_warping

    In time series analysis, dynamic time warping (DTW) is an algorithm for measuring similarity between two temporal sequences, which may vary in speed. For instance, similarities in walking could be detected using DTW, even if one person was walking faster than the other, or if there were accelerations and decelerations during the course of an ...

  6. Timewarp (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Timewarp_(computer_graphics)

    Rather than adjust the timing of every curve within the subsection, a timewarp curve can be applied to the model section in question, adjusting the flow of time itself for that element, with respect to the timing of the other, unaffected elements.

  7. Spacetime diagram - Wikipedia

    en.wikipedia.org/wiki/Spacetime_diagram

    A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity.Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations.

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  9. Word-representable graph - Wikipedia

    en.wikipedia.org/wiki/Word-representable_graph

    In the mathematical field of graph theory, a word-representable graph is a graph that can be characterized by a word (or sequence) whose entries alternate in a prescribed way. In particular, if the vertex set of the graph is V , one should be able to choose a word w over the alphabet V such that letters a and b alternate in w if and only if the ...
